Question

What is the use of rheostat?​

Answer 1

Answer:

Hi your answer is as follows

Explanation:

Rheostat is also known as an adjustable or variable resistor.

It is used to control the electrical resistance of a circuit without interrupting the flow of current. Rheostat has 3 terminals and usually consist of a resistive wire wrapped to form a toroid coil with a wiper that slides along the surface of the coil.

Answer 2

Explanation:

The most prominent use of rheostats is to control the current. To limit the current so as to prevent high current faults, rheostats are used. According to the current requirement the size of the rheostat to be used is chosen. For example, for high current circuits, large rheostats are used. They are also used in dimmer circuits,speed control circuits for motors, heaters and ovens.
