Function Of Variable Resistor In A Circuit

Simply put a variable resistor is able to have its electrical resistance adjusted. They specifically work with voltage and currents that are a part of the circuit.

These devices are used when working with electrical circuitry because they help to control voltage andor currents.

Function of variable resistor in a circuit. A movable metal is rotated in clockwise or anticlockwise direction that changes the resistance of preset. A variable resistor is the type of resistor which changes the flow of current in a controlled manner by offering a wide range of resistances. The electrical resistance is varied by sliding a wiper contact along a resistance track.

It can be used as a three terminal as well as a two terminal device. A resistor is a specialized electrical component that provides resistance as a circuit element. Resistors have two primary functions within a circuit.

Definition of variable resistor. 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. On an electronic guitar you can use a potentiometer.

There are 3 pinsterminals on a preset. This is where i first used variable resistors in the form of a potentiometer. A variable resistor is a device that is used to change the resistance according to our needs in an electronic circuit.

Resistors are passive which means they are not affected by the current they carry. If 100k is written on preset it means that we can vary its resistance from 0 ohm to 100k. It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit.

Heres a few examples. As the resistance increases in the variable resistor the current through the circuit decreases and vice versa. It is an electronic component.

The maximum resistance that a preset can provide is written on it. Mostly they are used as a three terminal device. These resistors are generally of low values so that the over all performance of the circuit is not affected.

Resistors are usually made of metal or carbon wire. Variable resistors are mostly used for device calibration. Similarly in a low pass or high pass filter a variable resistor can be used to change the cutoff frequency of the filter on the.
