The rheostat is a variable resistor used to control the electric current by increasing or decreasing the resistance manually. It is a largesized resistor type used in applications that require current adjustment or resistance change. It is placed in series in a circuit. The current controlled by rheostat is greater than other variable resistor ...

A rheostat is a type of variable resistor. When placed into an electrical circuit, a rheostat can be used to adjust and control the amount of current flowing around it. They do this by varying the resistance on the circuit, without interrupting the supply of power. Rheostats are one common type of electromechanical variable resistor.

Rheostats vary the amount of electrical resistance in a circuit. They proved beneficial as the use of electrical power expanded in the late 1800s. Among their many applications, rheostats helped motors start safely, controlled motor speed, maintained a constant current in battery chargers, and adjusted volume and light levels. This rheostat was used as part of Edison's first threewire ...
