Question

What is the work of rehostat ..​

Answer 1

Answer:

it is a resistor which controls the current

Answer 2

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.

Explanation:

A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... In contrast to potentiometers, rheostats have to carry a significant current. Therefore they are mostly constructed as wire wound resistors
