What Does A Variable Resistor Do In An Electrical Circuit

The electrical resistance is varied by sliding a wiper contact along a resistance track. A variable resistor is very important.

Variable Resistor An Overview

As the resistance increases in the variable resistor the current through the circuit decreases and vice versa.

What does a variable resistor do in an electrical circuit. It can act as a control on the amount of current flowing. If you add some voltage to it nothing really happens. A variable resistor is very important in a circuit because it allows you to build a circuit with some degree of control.

It allows you to build a circuit with some degree of control. A resistor is a device that impedes or limits the flow of electrical current in a circuit. Definition of variable resistor.

Here is a picture of a variable resistor from a dimmer switch. For example a volume knob can be a variable resistor. It is an electronic component.

A variable resistor works by adjusting the path that current has to flow. What does the resistor do to my circuit. 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.

It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. Well maybe it gets warm but thats it. It converts the currents electrical energy into heat thermal energy.

They can also be used to control the voltage across devices in a circuit too. The resistor is a passive device and doesnt do anything actively to your circuit. It can act as a control on the amount of current flowing.

For example a volume knob can be a variable resistor. A resistor reduces the amount of energy in a circuit and pumps it out as a heat. Its actually a pretty boring device.

This depends mostly on the circuit it is used in.
