They are commonly equiped with a knob outside of a cabinet to enable the user to adjust the operation of a circuit. It is commonly used to change the value of current across a circuit or to act as a voltage divider.

These resistors are generally of low values so that the over all performance of the circuit is not affected.

What is the purpose of a variable resistor in a circuit. Definition of variable resistor it is an electronic component. Simply put a variable resistor is able to have its electrical resistance adjusted. Some of the popular types of variable resistors are.

It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. What is the purpose of a variable resistor in a circuit used for measuring the resistance of a component in the circuit. It is an electronic component.

The connection and purpose of a variable resistor in a circuit determines the type of variable resistor. Simply put a variable resistor is able to have its electrical resistance adjusted. A resistor when introduced in series with the supply terminals of the circuit helps in checking the sudden rise in voltage and averting a possible harm.

They are commonly equiped with a knob outside of a cabinet to enable the user to adjust the operation of a circuit. But every time i see a variable resister placed at the end of the circuit. A variable resistor is used in cicuits to vary the current passing through the resistor.

Definition of variable resistor. The electrical resistance is varied by sl. These devices are used when working with electrical circuitry because they help to control voltage andor currents.

I often see circuits like the one below in questions which ask where the ammeter and voltmeter should be placed to correctly calculate the resistance. The electrical resistance is varied by sliding a wiper contact along a resistance track. When all the three terminals are used in a circuit and the output voltage is taken from the moving terminal the variable resistor is known as a potentiometer.

They specifically work with voltage and currents that are a part of the circuit. They specifically work with voltage and currents that are a part of the circuit. 1 to dissipate extra power 2 for protection purpose 3 to oppose the current 4 to drop excessive voltage in the circuit.

These devices are used when working with electrical circuitry because they help to control voltage andor currents. It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. A variable resistor is used in cicuits to vary the current passing through the resistor.

It is commonly used to change the value of current across a circuit or to act as a voltage divider.
