In your daily life, you use many electronic appliances. Maximum appliances used at home consist of an electric component known as a resistor. These resistors are mostly used in heaters, light bulbs, microwaves, electric stoves, toasters, and other heating appliances. In an electronic circuit, the flow of the current or limits of current is done by a resistor. To provide a particular voltage range for an active device, resistors are used as transistors.

In an electronic circuit, the flow of the current or limits of current is done by a resistor. To provide a particular voltage range for an active device, resistors are used as transistors.
Resistors are classified into two types. These types of resistors are further divided into subcategories. The types of resistors are as follows:
The current in the linear resistor will be directly proportional to the voltage applied to the resistor. The resultant graph of the linear resistor will be between the current (I) and voltage (V). The linear resistor graph will have a straight I-V curve.
Linear resistors are further divided into two types:
Fixed resistors have specific values, and these specific values cannot be changed. These fixed resistors are used for the appliance which never needs to change their value.
Variable resistors have values that can be varied or changed, and these variable values can be changed using a dial, screw, button, or knob. These variable resistors are used for appliances like radios with knobs, lights with switches, and television.
The current in the non-linear resistor will be indirectly proportional to the voltage applied to the resistor. Current In the resistor changes with the exchange in the temperature or voltage exchange. Values of non-linear resistors aren’t changed according to Ohm’s law. The resultant graph of the non-linear resistor will be between the current (I) and voltage (V). The non-linear resistor graph will have a non-linear I-V curve.
Non-linear resistors are further divided into three types:
Thermistors resistors are a kind of variable resistors. Thermistors identify the temperature change. These thermistor resistors have two terminals, and it is sensitive to temperature. The resistance value of the thermistor resistor is inversely proportional to the temperature.
A non-linear varistor resistor is made of semiconductors. The current through the varistor depends non-linearly on the voltage applied across the resistor. The most commonly used form for the varistor resistor is MOV or metal oxide varistor.
Photo resistors are also called LDR (light-dependent resistors). The other names of the photo resistors are photoconductive cells and light-controlled variable resistors. The photoresistor’s resistance decreases with an increase in the intensity of the incident light. So, the photoresistor’s resistance is inversely proportional to the intensity of the incident light.
The fixed and variable resistors are types of resistors called linear resistors. These fixed and variable resistors are further classified into sub-categories.
There are seven types of resistor, including the fixed resistor, which are as follows:
A form of a passive component is called a wire-wound resistor. A wire wound resistor is created by wrapping metal wire around a metal core. The metal wire serves as the electric current’s resistive component. Thus, the metal wire restricts a specific level of electric current. As a non-conductive substance, the metal core is placed. As a result, it blocks the flow of electric current.
The most precise and reliable parts to employ to limit the flow of electric current to a specific level are foil resistors. Compared to other types of resistors, foil resistors generate little noise. The TCR (Temperature Coefficient of Resistance) of foil resistors is low.
A passive component that limits the flow of electric current to a set level is a resistor made of carbon called a carbon composition resistor. The cylindrical resistive element used to create the carbon composition resistors has integrated metal end caps. The ceramic and carbon powder combination is used to create the cylindrical resistive element of the carbon composition resistor. The carbon powder effectively conducts electric current.
The carbon film resistor is the most common type of resistor used in electrical circuits. The carbon film is applied to a ceramic substrate to create the carbon film resistors. The ceramic substrate serves as an electrical current insulator, while the carbon sheet functions as a resistive element to the current.
A form of a passive component known as a metal film resistor uses metal film to limit the flow of electric current to a specific level. In contrast to metal film resistors, which use chromium, nickel, tin, and antimony to create their films, carbon is used to create the film in carbon film resistors. The TCR (temperature coefficient of resistance) of metal film resistors is low.
The metal glaze resistor is a passive component used to limit the flow of electric current to a certain level by combining glass powder with metal particles. Low TCR (temperature coefficient of resistance) for metal glaze resistors.
A form of a passive component known as a metal oxide film resistor uses metal oxide film as the resistive element to limit the flow of electric current to a specific level. Metal oxide film resistor construction is virtually identical to metal film resistors.
There are seven types of the resistor of variable resistor, which are as follows:
Three terminals make up the potentiometer, two fixed and one movable. The track’s two resistive ends are linked to the potentiometer’s two fixed terminals, while the third terminal is connected to the slider or sliding wiper. The current flow in the potentiometer decreases when the resistance of the potentiometer is increased.
Humistor name is the combination of humidity and resistor. Humidity affects humistors quite strongly. Resistive humidity sensors and humidity-sensitive resistors are other names for humidistats.
Rheostats are built in a manner that is virtually identical to potentiometers. However, we utilize two terminals of a rheostat to act. The length of the resistive element or track through which the electric current flows determines the rheostat’s resistance.
Resistance of Thermistors depends on the surrounding temperature change. Positive temperature coefficient (PTC) and negative temperature coefficient (NTC) thermistors are the two types of thermometers. While PTC thermistors experience an increase in resistance as the temperature rises, NTC thermistors experience a reduction in resistance as the temperature rises.
The resistance of the magneto resistor varies when a magnetic field is supplied to the magneto resistor. Similarly, the magneto resistor’s resistance dropped as the magnetic field’s strength increased.
The word photoresistor is the combination of the terms photon and resistor. The photoresistor experiences a change in resistance when light energy is applied. As the applied light intensity rises, the photo resistor’s resistance falls.
As the name indicates, the force-sensitive resistors are extremely sensitive to the applied force. Force sensors, pressure sensors, force-sensing resistors, or FSR are other names for force-sensitive resistors.
Things to Consider When Using Various Types of Resistors
Power dissipation and temperature coefficients are the two factors to be mindful of when using a type of resistor.
Power Dissipation: Power dissipation is an important consideration when selecting a resistor. Always select a resistor with a lower power rating than the current being passed through it. So, choose a resistor with a power rating at least twice as high.
Temperature Coefficients: The most important thing to remember when working with resistors is that they must be used at high temperatures or else the resistance will flow dramatically. The temperature coefficient of a resistor is classified as either negative or positive (PTC).
The value of the resistor isn’t displayed outside. Through the color pattern, the resistance of the resistor can be calculated. The (PTH) plated-through-hole resistors use the color coding system; these colors add flair to the circuit when connected. In the case of (SMD) surface mount device resistors, they have their value marking system.
The value of the resistor of the deviation from the nominal value is known as the tolerance of resistors. This value is expressed with the ±% symbol. The resistor’s tolerance is used to identify the resistor, giving a more accurate resistance reading.
Tolerance of the resistor according to the color:
ColorTolerance
Brown±1%
Red±2 %
Gold±5%
Silver±10%
Wire applications wrapped resistors kind of include shunt with ampere meters which essentially used for accurate measurement, high sensitivity very balanced current regulation in a generally major way.
Photo resistors are used in various products, including photography equipment, burglar alarms, and flame detectors in a pretty big way.
Voltmeter and temperature control generally is controlled by resistors, contrary to popular belief.
Amplifiers, telephony, oscillators, and digital multimeters all need resistors, which is particularly significant. They are also utilized in transmitters, demodulators, and modulators, which are particularly fairly significant.
Resistors are part of appliances used in daily life. These resistors are used in circuits. Practical work with resistors will help to know the usage and working of the resistor in the circuit. In physics, resistors are to know the behavior of different resistors, i.e., the flow of the current, voltage flow, etc.
There are many different types of resistors. Each type of resistor is used in different circuits according to their behavior. To know which type of resistor should be used in the circuit, the color of the type of resistor table should be referred to.
A. There are many types of resistors. The main classification of resistors is two types that are linear and nonlinear. These are further divided into subcategories. The linear resistors are divided into fixed and variable resistors. The nonlinear resistors are divided into a thermistor, photoresistor, varistor, and surface mount resistor.

The limited current should supply from the charger as a wire wound resistor is created by wrapping metal wire around a metal core. The metal wire serves as the electric current’s resistive component. Thus, the metal wire restricts a specific level of electric current. As a non-conductive substance, the metal core is placed. As a result, it blocks the flow of electric current. So the chargers will be working without any high voltages.

Metal film resistors.
Thermal Fuse Resistors
Resistors are components used to resist the flow of electric current and have a stated value of RESISTANCE. Many types of resistors are used having different uses and construction. The most common types have a fixed value of resistance so are often called fixed resistors. They are shown on circuit schematic diagrams (theoretical diagrams that show how the circuit components are connected electrically, rather than what a circuit looks like physically) using one of the symbols shown in Fig 2.0.1.
Various types of fixed resistorstypes of fixed resistors are used in circuits, they are the most numerous of all electronic components and their most common job is to reduce voltages and currents around a circuit so that ‘active components’, transistors and integrated circuits for example, that carry out tasks such as producing or amplifying signals within the circuit are supplied with the correct voltages and currents to work properly.
Resistors are also used in conjunction with other components such as inductors and capacitors to process signals in many ways.
Because resistors are ‘passive components’ they cannot amplify or increase voltages currents or signals, they can only reduce them. Nevertheless they are a most essential part of any electronic circuit.
Many modern circuits use SMT resistors. Their manufacture involves depositing a film of resistive material such as tin oxide on a tiny ceramic chip. The edges of the resistor are then accurately ground, or cut with a laser to give a precise resistance (which depends on the width of the resistor film), across the ends of the device. Tolerances may be as low as ±0.02%. Contacts at each end are soldered directly onto the conductive print on the circuit board, usually by automatic assembly methods. SMT resistors normally have a very low power dissipation. Their main advantage is that very high component density can be achieved.

Similar construction to Metal film resistors but generally with wider tolerance (typically +/- 5%), shown in Fig. 2.0.2 mounted on paper strips for machine insertion into printed circuit boards. Small resistors are extremely inexpensive components and are also often sold in batches of 10s or 100s in this form for easier handling.

Carbon composition is the oldest design and usually the cheapest of the resistors. Carbon granules are mixed with a filler material and inserted into a tubular casing. In earlier types vulcanised rubber was used but in modern designs the carbon is mixed with a ceramic filler. The value of resistance is determined by the amount of carbon added to the filler mixture. Carbon composition resistors do not have the close tolerances of either carbon or metal film types. Typical tolerances are +/-10% or 20%. One advantage however is that they are better suited to applications involving large voltage pulses than the more modern types.

Carbon composition, carbon and metal film resistors are available in a range of power ratings, from 0.125W to 5W. In a resistor, the power that the resistor must dissipate (get rid of as heat) depends on the voltage difference (V) across the resistor, and the current (I) flowing through it. These are multiplied together to obtain the amount of power (P) that must be dissipated using the formula P = IV. For any particular type or value of resistor, the greater the power rating, the larger the physical size of the resistor.
Wirewound resistors are very variable in construction and physical appearance. Their resistive elements are commonly lengths of wire, usually an alloy such as Nichrome (Nickel/Chromium) or Manganin (Copper/Nickel/Manganese) wrapped around a ceramic or glass fibre rod or tube and coated in an insulating flameproof cement film. They are normally available in quite low values of resistance (single ohms to a few Kilohms) but can dissipate large amounts of power. In use they may get very hot.
For this reason high power wirewound resistors may be housed in a finned metal case that can be bolted to a metal chassis to dissipate the heat generated as effectively as possible. With all types of wirewound resistor, fire protection is important and flame proof cases or coatings are vital. Lead-out wires are normally welded rather than soldered to the resistor.
These resistors are made from small rods of ceramic coated with metal such as a nickel alloy or a metal oxide such as tin oxide. The value of resistance is controlled firstly by the thickness of the coating layer; the thicker the layer, the lower the value of resistance. Also by a fine spiral groove cut along the rod using a laser or diamond cutter to cut the carbon or metal coating effectively into a long spiral strip, which forms the resistor. Metal film resistors can be obtained in a wide range of resistance values from a few Ohms to tens of millions of Ohms with a very small TOLERANCE. For example a typical value might be 100KΩ ±1% or less i.e. for a stated value of 100KΩ the actual value will be between 99KΩ and 101KΩ. Note that although the body colour (the colour of the laquer coating) on metal film resistors is often grey, this is not a reliable guide. Small carbon, metal and oxide resistors may be made in various body colours such as dark red, brown, blue, green, grey, cream or white.
A wirewound resistor can have a smaller physical size for a given power rating than carbon composition or film resistors, compare this 5W resistor with the 1W resistor (labelled 3 in Fig.2.0.2). Wirewound resistors however, do not not have the close tolerance of composition or film types. This 4R7 resistor has a tolerance of ±10%.
Wirewound resistors usually have a resistance range from around 1Ω to about 50KΩ. Because they use a coil of wire as their resistive element they tend to act as inductors to some degree. This limits their use to low frequency circuits up to around a few tens of kiloHertz (kHz). This example, available in power ratings up to 25W, is for mounting on a printed circuit board and to prevent heat damage to the board, the specially shaped legs ensure an air gap between the resistor and the board. The whole resistor is enclosed in a flameproof ceramic layer.
Metal film resistors are also available in high power types with power ratings less than wirewound types (typically less than 5W) but having closer tolerances.
In this fusible resistor, the current flowing through the resistor first flows through a spring loaded connection that is positioned close to the body of the resistor. The heat generated by the wirewound resistor under normal conditions would not be sufficient to melt the blob of solder holding a spring wire in place. If too much current flows through the resistor it overheats, the solder melts and the wire springs up, opening the connection and stopping the current. This then requires a service technician to find the cause of the over-current before re-soldering the spring connection to restore normal operation. It is important to use the correct type of solder (usually stated in the service manual for the equipment) when re-soldering, since this will affect the temperature at which the spring opens.
Fixed resistors have a constant resistance value, while variable resistors allow for adjustable resistance, suiting different applications.
Resistors are crucial components in electronic circuits, controlling current flow and voltage levels. They come in various types, with fixed and variable resistors being two common classifications. This article will explore the differences between fixed and variable resistors and their respective applications.
What are Variable Resistance Transd..
What are Variable Resistance Transducers, Resistive Transducers, Resistive Sensors?
Fixed resistors have a constant resistance value that cannot be changed. They are used in a wide range of electronic circuits to perform tasks such as voltage division, current limiting, and signal attenuation. Some key features of fixed resistors include:
Constant resistance: The resistance value remains fixed and does not change during operation.
Various types: Fixed resistors come in different forms, such as carbon film, metal film, wirewound, and surface-mount, each with its unique properties and applications.
Range of values: Fixed resistors are available in a broad range of resistance values and tolerances, allowing them to be used in diverse applications.
Variable resistors, also known as potentiometers or rheostats, have an adjustable resistance value. They are used in applications where it’s necessary to vary resistance, such as controlling volume, tuning, or adjusting signal levels. Some key features of variable resistors include:
Adjustable resistance: The resistance value can be altered by adjusting a knob, slider, or screw, depending on the design.
Three-terminal device: Variable resistors typically have three terminals, with the center terminal (wiper) providing the adjustable output voltage or resistance value.
Various designs: Variable resistors come in different forms, such as rotary, linear, and digital potentiometers, each suited for specific applications.
Fixed and variable resistors find use in various applications:
Fixed resistor applications: Voltage dividers, current limiters, biasing, signal attenuation, and feedback loops in amplifiers.
Variable resistor applications: Volume control in audio equipment, tuning in radios, light dimmers, and sensor calibration.
The main difference between fixed and variable resistors lies in their adjustability. Fixed resistors have a constant resistance value, while variable resistors allow for adjustment of their resistance. Understanding the differences and applications of these resistors will enable you to choose the right component for your specific circuit design needs.

Various types of fixed resistors are used in circuits, they are the most numerous of all electronic components and their most common job is to reduce voltages and currents around a circuit so that ‘active components’, transistors and integrated circuits for example, that carry out tasks such as producing or amplifying signals within the circuit are supplied with the correct voltages and currents to work properly.
Resistors are also used in conjunction with other components such as inductors and capacitors to process signals in many ways.
Because resistors are ‘passive components’ they cannot amplify or increase voltages currents or signals, they can only reduce them. Nevertheless they are a most essential part of any electronic circuit.
Many modern circuits use SMT resistors. Their manufacture involves depositing a film of resistive material such as tin oxide on a tiny ceramic chip. The edges of the resistor are then accurately ground, or cut with a laser to give a precise resistance (which depends on the width of the resistor film), across the ends of the device. Tolerances may be as low as ±0.02%. Contacts at each end are soldered directly onto the conductive print on the circuit board, usually by automatic assembly methods. SMT resistors normally have a very low power dissipation. Their main advantage is that very high component density can be achieved.

Similar construction to Metal film resistors but generally with wider tolerance (typically +/- 5%), shown in Fig. 2.0.2 mounted on paper strips for machine insertion into printed circuit boards. Small resistors are extremely inexpensive components and are also often sold in batches of 10s or 100s in this form for easier handling.

Carbon composition is the oldest design and usually the cheapest of the resistors. Carbon granules are mixed with a filler material and inserted into a tubular casing. In earlier types vulcanised rubber was used but in modern designs the carbon is mixed with a ceramic filler. The value of resistance is determined by the amount of carbon added to the filler mixture. Carbon composition resistors do not have the close tolerances of either carbon or metal film types. Typical tolerances are +/-10% or 20%. One advantage however is that they are better suited to applications involving large voltage pulses than the more modern types.

Carbon composition, carbon and metal film resistors are available in a range of power ratings, from 0.125W to 5W. In a resistor, the power that the resistor must dissipate (get rid of as heat) depends on the voltage difference (V) across the resistor, and the current (I) flowing through it. These are multiplied together to obtain the amount of power (P) that must be dissipated using the formula P = IV. For any particular type or value of resistor, the greater the power rating, the larger the physical size of the resistor.
Wirewound resistors are very variable in construction and physical appearance. Their resistive elements are commonly lengths of wire, usually an alloy such as Nichrome (Nickel/Chromium) or Manganin (Copper/Nickel/Manganese) wrapped around a ceramic or glass fibre rod or tube and coated in an insulating flameproof cement film. They are normally available in quite low values of resistance (single ohms to a few Kilohms) but can dissipate large amounts of power. In use they may get very hot.
For this reason high power wirewound resistors may be housed in a finned metal case that can be bolted to a metal chassis to dissipate the heat generated as effectively as possible. With all types of wirewound resistor, fire protection is important and flame proof cases or coatings are vital. Lead-out wires are normally welded rather than soldered to the resistor.
These resistors are made from small rods of ceramic coated with metal such as a nickel alloy or a metal oxide such as tin oxide. The value of resistance is controlled firstly by the thickness of the coating layer; the thicker the layer, the lower the value of resistance. Also by a fine spiral groove cut along the rod using a laser or diamond cutter to cut the carbon or metal coating effectively into a long spiral strip, which forms the resistor. Metal film resistors can be obtained in a wide range of resistance values from a few Ohms to tens of millions of Ohms with a very small TOLERANCE. For example a typical value might be 100KΩ ±1% or less i.e. for a stated value of 100KΩ the actual value will be between 99KΩ and 101KΩ. Note that although the body colour (the colour of the laquer coating) on metal film resistors is often grey, this is not a reliable guide. Small carbon, metal and oxide resistors may be made in various body colours such as dark red, brown, blue, green, grey, cream or white.
In your daily life, you use many electronic appliances. Maximum appliances used at home consist of an electric component known as a resistor. These resistors are mostly used in heaters, light bulbs, microwaves, electric stoves, toasters, and other heating appliances. In an electronic circuit, the flow of the current or limits of current is done by a resistor. To provide a particular voltage range for an active device, resistors are used as transistors.
Resistors are classified into two types. These types of resistors are further divided into subcategories. The types of resistors are as follows:
The current in the linear resistor will be directly proportional to the voltage applied to the resistor. The resultant graph of the linear resistor will be between the current (I) and voltage (V). The linear resistor graph will have a straight I-V curve.
Linear resistors are further divided into two types:
Fixed resistors have specific values, and these specific values cannot be changed. These fixed resistors are used for the appliance which never needs to change their value.
Variable resistors have values that can be varied or changed, and these variable values can be changed using a dial, screw, button, or knob. These variable resistors are used for appliances like radios with knobs, lights with switches, and television.
The current in the non-linear resistor will be indirectly proportional to the voltage applied to the resistor. Current In the resistor changes with the exchange in the temperature or voltage exchange. Values of non-linear resistors aren’t changed according to Ohm’s law. The resultant graph of the non-linear resistor will be between the current (I) and voltage (V). The non-linear resistor graph will have a non-linear I-V curve.
Non-linear resistors are further divided into three types:
Thermistors resistors are a kind of variable resistors. Thermistors identify the temperature change. These thermistor resistors have two terminals, and it is sensitive to temperature. The resistance value of the thermistor resistor is inversely proportional to the temperature.
A non-linear varistor resistor is made of semiconductors. The current through the varistor depends non-linearly on the voltage applied across the resistor. The most commonly used form for the varistor resistor is MOV or metal oxide varistor.
Photo resistors are also called LDR (light-dependent resistors). The other names of the photo resistors are photoconductive cells and light-controlled variable resistors. The photoresistor’s resistance decreases with an increase in the intensity of the incident light. So, the photoresistor’s resistance is inversely proportional to the intensity of the incident light.
The fixed and variable resistors are types of resistors called linear resistors. These fixed and variable resistors are further classified into sub-categories.
There are seven types of resistor, including the fixed resistor, which are as follows:
A form of a passive component is called a wire-wound resistor. A wire wound resistor is created by wrapping metal wire around a metal core. The metal wire serves as the electric current’s resistive component. Thus, the metal wire restricts a specific level of electric current. As a non-conductive substance, the metal core is placed. As a result, it blocks the flow of electric current.
The most precise and reliable parts to employ to limit the flow of electric current to a specific level are foil resistors. Compared to other types of resistors, foil resistors generate little noise. The TCR (Temperature Coefficient of Resistance) of foil resistors is low.
A passive component that limits the flow of electric current to a set level is a resistor made of carbon called a carbon composition resistor. The cylindrical resistive element used to create the carbon composition resistors has integrated metal end caps. The ceramic and carbon powder combination is used to create the cylindrical resistive element of the carbon composition resistor. The carbon powder effectively conducts electric current.
The carbon film resistor is the most common type of resistor used in electrical circuits. The carbon film is applied to a ceramic substrate to create the carbon film resistors. The ceramic substrate serves as an electrical current insulator, while the carbon sheet functions as a resistive element to the current.
A form of a passive component known as a metal film resistor uses metal film to limit the flow of electric current to a specific level. In contrast to metal film resistors, which use chromium, nickel, tin, and antimony to create their films, carbon is used to create the film in carbon film resistors. The TCR (temperature coefficient of resistance) of metal film resistors is low.
The metal glaze resistormetal glaze resistor is a passive component used to limit the flow of electric current to a certain level by combining glass powder with metal particles. Low TCR (temperature coefficient of resistance) for metal glaze resistors.
A form of a passive component known as a metal oxide film resistor uses metal oxide film as the resistive element to limit the flow of electric current to a specific level. Metal oxide film resistor construction is virtually identical to metal film resistors.
There are seven types of the resistor of variable resistor, which are as follows:
Three terminals make up the potentiometer, two fixed and one movable. The track’s two resistive ends are linked to the potentiometer’s two fixed terminals, while the third terminal is connected to the slider or sliding wiper. The current flow in the potentiometer decreases when the resistance of the potentiometer is increased.
Humistor name is the combination of humidity and resistor. Humidity affects humistors quite strongly. Resistive humidity sensors and humidity-sensitive resistors are other names for humidistats.
Rheostats are built in a manner that is virtually identical to potentiometers. However, we utilize two terminals of a rheostat to act. The length of the resistive element or track through which the electric current flows determines the rheostat’s resistance.
Resistance of Thermistors depends on the surrounding temperature change. Positive temperature coefficient (PTC) and negative temperature coefficient (NTC) thermistors are the two types of thermometers. While PTC thermistors experience an increase in resistance as the temperature rises, NTC thermistors experience a reduction in resistance as the temperature rises.
The resistance of the magneto resistor varies when a magnetic field is supplied to the magneto resistor. Similarly, the magneto resistor’s resistance dropped as the magnetic field’s strength increased.
The word photoresistor is the combination of the terms photon and resistor. The photoresistor experiences a change in resistance when light energy is applied. As the applied light intensity rises, the photo resistor’s resistance falls.
As the name indicates, the force-sensitive resistors are extremely sensitive to the applied force. Force sensors, pressure sensors, force-sensing resistors, or FSR are other names for force-sensitive resistors.
Things to Consider When Using Various Types of Resistors
Power dissipation and temperature coefficients are the two factors to be mindful of when using a type of resistor.
Power Dissipation: Power dissipation is an important consideration when selecting a resistor. Always select a resistor with a lower power rating than the current being passed through it. So, choose a resistor with a power rating at least twice as high.
Temperature Coefficients: The most important thing to remember when working with resistors is that they must be used at high temperatures or else the resistance will flow dramatically. The temperature coefficient of a resistor is classified as either negative or positive (PTC).
The value of the resistor isn’t displayed outside. Through the color pattern, the resistance of the resistor can be calculated. The (PTH) plated-through-hole resistors use the color coding system; these colors add flair to the circuit when connected. In the case of (SMD) surface mount device resistors, they have their value marking system.
The value of the resistor of the deviation from the nominal value is known as the tolerance of resistors. This value is expressed with the ±% symbol. The resistor’s tolerance is used to identify the resistor, giving a more accurate resistance reading.
Tolerance of the resistor according to the color:
ColorTolerance
Brown±1%
Red±2 %
Gold±5%
Silver±10%
Wire applications wrapped resistors kind of include shunt with ampere meters which essentially used for accurate measurement, high sensitivity very balanced current regulation in a generally major way.
Photo resistors are used in various products, including photography equipment, burglar alarms, and flame detectors in a pretty big way.
Voltmeter and temperature control generally is controlled by resistors, contrary to popular belief.
Amplifiers, telephony, oscillators, and digital multimeters all need resistors, which is particularly significant. They are also utilized in transmitters, demodulators, and modulators, which are particularly fairly significant.
Resistors are part of appliances used in daily life. These resistors are used in circuits. Practical work with resistors will help to know the usage and working of the resistor in the circuit. In physics, resistors are to know the behavior of different resistors, i.e., the flow of the current, voltage flow, etc.
There are many different types of resistors. Each type of resistor is used in different circuits according to their behavior. To know which type of resistor should be used in the circuit, the color of the type of resistor table should be referred to.
A. There are many types of resistors. The main classification of resistors is two types that are linear and nonlinear. These are further divided into subcategories. The linear resistors are divided into fixed and variable resistors. The nonlinear resistors are divided into a thermistor, photoresistor, varistor, and surface mount resistor.
A. Flameproof wire wound resistors are used in the chargers as chargers are the input devices. The limited current should supply from the charger as a wire wound resistor is created by wrapping metal wire around a metal core. The metal wire serves as the electric current’s resistive component. Thus, the metal wire restricts a specific level of electric current. As a non-conductive substance, the metal core is placed. As a result, it blocks the flow of electric current. So the chargers will be working without any high voltages.
Ans. The type of resistor used in a bulb is tungsten. The filament in the bulb doesn’t have a specific resistance level, so when the voltage through the bulb has increased, the current is also increased. The increase in current results in the temperature of the bulb. As a result, the bulb glows.

Thermal Fuse Resistors
Resistors are components used to resist the flow of electric current and have a stated value of RESISTANCE. Many types of resistors are used having different uses and construction. The most common types have a fixed value of resistance so are often called fixed resistors. They are shown on circuit schematic diagrams (theoretical diagrams that show how the circuit components are connected electrically, rather than what a circuit looks like physically) using one of the symbols shown in Fig 2.0.1.

Because resistors are ‘passive components’ they cannot amplify or increase voltages currents or signals, they can only reduce them. Nevertheless they are a most essential part of any electronic circuit.
Many modern circuits use SMT resistors. Their manufacture involves depositing a film of resistive material such as tin oxide on a tiny ceramic chip. The edges of the resistor are then accurately ground, or cut with a laser to give a precise resistance (which depends on the width of the resistor film), across the ends of the device. Tolerances may be as low as ±0.02%. Contacts at each end are soldered directly onto the conductive print on the circuit board, usually by automatic assembly methods. SMT resistors normally have a very low power dissipation. Their main advantage is that very high component density can be achieved.

Carbon composition, carbon and metal film resistors are available in a range of power ratings, from 0.125W to 5W. In a resistor, the power that the resistor must dissipate (get rid of as heat) depends on the voltage difference (V) across the resistor, and the current (I) flowing through it. These are multiplied together to obtain the amount of power (P) that must be dissipated using the formula P = IV.

They are normally available in quite low values of resistance (single ohms to a few Kilohms) but can dissipate large amounts of power. In use they may get very hot.
For this reason high power wirewound resistors may be housed in a finned metal case that can be bolted to a metal chassis to dissipate the heat generated as effectively as possible. With all types of wirewound resistor, fire protection is important and flame proof cases or coatings are vital. Lead-out wires are normally welded rather than soldered to the resistor.
These resistors are made from small rods of ceramic coated with metal such as a nickel alloy or a metal oxide such as tin oxide. The value of resistance is controlled firstly by the thickness of the coating layer; the thicker the layer, the lower the value of resistance. Also by a fine spiral groove cut along the rod using a laser or diamond cutter to cut the carbon or metal coating effectively into a long spiral strip, which forms the resistor. Metal film resistors can be obtained in a wide range of resistance values from a few Ohms to tens of millions of Ohms with a very small TOLERANCE. For example a typical value might be 100KΩ ±1% or less i.e. for a stated value of 100KΩ the actual value will be between 99KΩ and 101KΩ. Note that although the body colour (the colour of the laquer coating) on metal film resistors is often grey, this is not a reliable guide. Small carbon, metal and oxide resistors may be made in various body colours such as dark red, brown, blue, green, grey, cream or white.
A wirewound resistor can have a smaller physical size for a given power rating than carbon composition or film resistors, compare this 5W resistor with the 1W resistor (labelled 3 in Fig.2.0.2). Wirewound resistors however, do not not have the close tolerance of composition or film types. This 4R7 resistor has a tolerance of ±10%.
Wirewound resistors usually have a resistance range from around 1Ω to about 50KΩ. Because they use a coil of wire as their resistive element they tend to act as inductors to some degree. This limits their use to low frequency circuits up to around a few tens of kiloHertz (kHz). This example, available in power ratings up to 25W, is for mounting on a printed circuit board and to prevent heat damage to the board, the specially shaped legs ensure an air gap between the resistor and the board. The whole resistor is enclosed in a flameproof ceramic layer.
Metal film resistors are also available in high power types with power ratings less than wirewound types (typically less than 5W) but having closer tolerances.
In this fusible resistor, the current flowing through the resistor first flows through a spring loaded connection that is positioned close to the body of the resistor. The heat generated by the wirewound resistor under normal conditions would not be sufficient to melt the blob of solder holding a spring wire in place. If too much current flows through the resistor it overheats, the solder melts and the wire springs up, opening the connection and stopping the current. This then requires a service technician to find the cause of the over-current before re-soldering the spring connection to restore normal operation. It is important to use the correct type of solder (usually stated in the service manual for the equipment) when re-soldering, since this will affect the temperature at which the spring opens.
Fixed resistors have a constant resistance value, while variable resistors allow for adjustable resistance, suiting different applications.
Resistors are crucial components in electronic circuits, controlling current flow and voltage levels. They come in various types, with fixed and variable resistors being two common classifications.

Adjustable resistance: The resistance value can be altered by adjusting a knob, slider, or screw, depending on the design.
Three-terminal device: Variable resistors typically have three terminals, with the center terminal (wiper) providing the adjustable output voltage or resistance value.
Various designs: Variable resistors come in different forms, such as rotary, linear, and digital potentiometers, each suited for specific applications.
Fixed and variable resistors find use in various applications:
Fixed resistor applications: Voltage dividers, current limiters, biasing, signal attenuation, and feedback loops in amplifiers.
Variable resistor applications: Volume control in audio equipment, tuning in radios, light dimmers, and sensor calibration.
The main difference between fixed and variable resistors lies in their adjustability. Fixed resistors have a constant resistance value, while variable resistors allow for adjustment of their resistance. Understanding the differences and applications of these resistors will enable you to choose the right component for your specific circuit design needs.
