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.heostat. an electric device for controlling and limiting current or voltage in an electric circuit. The principal component of a rheostat is a conducting element with variable resistance. The magnitude of this resistance may be varied smoothly or in discrete steps.
