Question

An electric motor is not a part of which one of the following electrical appliances:

  1. Washing machine
  2. Grinder
  3. Fan
  4. Heater

hintHint:

Heating effect of electric current does not observed in electric motor.

The correct answer is: Heater


    • Electric motor is a device which converts electrical energy into mechanical energy.
    •  Heating effect of electric current does not observed in electric motor.
    • In washing machine ,fan ,grinder electrical energy is converted to mechanical energy 
    • But in Heater electrical energy is converted to heat energy hence in Heater electric motor is not used
