How do you use a variable resistor?
How do you use a variable resistor? When used as a variable resistor, connections are made to only one end of the resistive track (either pin 1 or pin 3) and the wiper (pin 2) as shown. The position of the wiper is used to vary or change the amount of effective resistance connected between itself, the movable contact, and the stationary fixed end. What is a variable resistor example? Variable Resistors are resistors whose resistance values can vary according to some factor applied to them. For example, potentiometers are variable resistors that changes when a user adjusts the knob....
