Answer:
A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... Therefore they are mostly constructed as wire wound resistors. Resistive wire is wound around an insulating ceramic core and the wiper slides over the windings.
