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?
- The bulb glows
- The bulb does not glow
- The bulb bursts
- The bulb fuses
Hint:
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.
