Question

The picture below shows a tester which can be used to identify if an object is a conductor or an insulator. What will happen if we connect the free ends of the wires to a plastic comb?

  1. The bulb glows
  2. The bulb does not glow
  3. The bulb bursts
  4. The bulb fuses

hintHint:

Comb is an insulator.

The correct answer is: The bulb does not glow


    • Comb is made up of plastic which is an insulator.
    • Insulators are unable to conduct electricity, therefore, plastic being an insulator will not be able to conduct the electricity from the cell to the bulb.
    • As a result, the bulb will not glow.
