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.
Rheostats and Resistance. A rheostat is a simple variable resistor with two contacts. A resistor is a device designed to resist the flow of electricity.The more resistance an electronic current has, the more slowly the current in it flows.nside a Rheostat. Most rheostats contain a strip of some substance with fairly high resistance, such as carbon. One of the rheostat's two contacts attaches to the end of the carbon strip. The other moves along the strip as you adjust the rheostat slider or knob.
