Question

The heating element is not a part of which one of the following electrical appliances?

  1. Electric cooker
  2. Electric toaster
  3. Electric fan
  4. Soldering iron

hintHint:

Electric fan

The correct answer is: Electric fan


    An electric fan converts electrical energy into mechanical energy.
    The electric fan works on the principle of electromagnetic induction. It works by the use of the electric motor. The coil of wires wounded on the metallic core is attached with the electric motor and then in this arrangement of the wires, the current is passed. Due to the passing of the current through the circular wires, rotational motion of the motor takes place. Thus, from the use of the electromagnetic induction, the electric fan works and give the useful output.
