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.
