What is a rheostat? 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 potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present.
Report Abuse. A rheostat is simply a coil of resistance wire with a slider on it so that the resistance can be varied. The list of ways that it can be used is very long. Prior to solid state devices they have been used to control lighting or battery charging. speed control of motors. production of variable emf etc.eport Abuse.
