Answer 1

Answer:

It is used to control the electrical resistance of a circuit without interrupting the flow of current.

Explanation:

Answer 2

Answer:

the purpose of the rheostat is provide variable resistance in the circuit leading to an ability to control the amount of current flowing through the circuit.

For example: the fan regulator is actually a rheostat, it regulates the total resistance in the circuit, and hence regulates fan speed
