Variable Resistor Function
A variable resistor is called a potentiometer or pot for short. They can also be used to control the voltage across devices in a circuit too. Potentiometer Preset Potentiometers And Rheostats Difference Between Potentiometer And Rheostat What Is The Difference Between A Rheostat And A Variable Considering their functions there are various types of these resistors to be found. Variable resistor function . It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. Either side of the variable resistor may be attached to the circuit board with the remaining side unattached or grounded. A common type of variable resistor is found in the volume control on a radio. It consists of a bare fixed resistance conductor with a terminal at each end plus a conductive wiper arm...
