Question

In the picture of a simple circuit shown below, the light does not glow _____.

  1. If the paper clip is replaced by a safety pin
  2. If the cardboard piece is replaced by a piece of thermocol
  3. If the paper clip is replaced by a rubber band
  4. If the cell is replaced by a battery of two cells

hintHint:

Bulb will not glow if there is an insulator is present in a circuit.

The correct answer is: If the paper clip is replaced by a rubber band


    • Rubber being an insulator will not be able to conduct electricity.
    • Therefore, when paper clip is replaced with rubber in a switch, the bulb will not glow.
