Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls.

Resistors are one of the fundamental components used in electronic circuits ... way for a resistor to work. In previous articles I talked about fixed value resistors as well as variable resistors.

Vishay’s ISOA200 thick-film power resistors with optional NTC thermistor and phase-change thermal interface material saves ...

the other with two lamps You could increase or decrease the resistance in a circuit by using a variable resistor (also known as a rheostat).

When we turn on the circuit, the galvanometer would ... Stretching a strain gauge causes a change in its resistance, hence a strain gauge is a variable resistor. Either one, two or all four ...
