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.
Typically a rheostat consists of a resistance element equipped with two contacts, or terminals, by which it is attached to a circuit: a fixed contact at one end and a sliding contact that can be moved along the resistance element. Electric current enters and leaves the resistance element through the contacts.
