A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption.The construction is very similar to the construction of a potentiometer s. It uses only two connections, even when 3 terminals (as in a potentiometer) are present. rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption.
Rheostat, adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit. The rheostat can adjust generator characteristics, dim lights, and start or control the speed of motors. Its resistance element can be a metal wire or ribbon, carbon, or a conducting liquid, depending on the application.
