What is a rheostat? Why is it connected in an electric circuit?​

Answer 1

Answer:

Rheostat, adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit. The rheostat can adjust generator characteristics, dim lights, and start or control the speed of motors.

Answer 2

Explanation:

ANSWER

rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... Therefore they are mostly constructed as wire wound resistors. Resistive wire is wound around an insulating ceramic core and the wiper slides over the windings.
