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 is generally used in the applications where high voltage or current is required. Rheostats are used in dim lights to change the intensity of light. If we increase the resistance of the rheostat, the flow of electric current through the light bulb decreases. As a result, the light brightness decreases.
