Rheostat, adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit.

The most common way to vary the resistance in a circuit is to use a rheostat, a two-terminal variable resistor. For low-power applications (less than about 1 watt) a three-terminal potentiometer is often used, with one terminal unconnected or connected to the wiper.
