Answer 2

Rheostat is not a type of energy source

Explanation:

• The correct option is C. Generators, batteries, and solar panels are all power or energy source. A rheostat is a variable resistor.

• Rheostats are electrical devices used to adjust the resistance or the current in an electric circuit.

• A rheostat, a two-terminal device, one lead is attached to the wiper and the other lead is attached to the resistance track. In rheostat, it changes  the resistance to change the amount of current following through the circuit.

Application of rheostat

• A rheostat is used to amplify or decrease the speed of electric motors.

• It is used when a high current or a high voltage is required.
