Question

State the function of rheostat in this lab experiment.​

Answer 1

Answer:

A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of a potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present

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. By changing the resistance you can control the current flowing through it. This can then be used to control downstream devices like transistors or lamps.
