Q.10 The handles of the tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber covers on them. Can you explain why?

(1) Plastic and rubber both are bad conductors of electricity.

(2) So, they do not allow current to pass through them.

(3) The handles of tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber cover on them so that they do allow the current to pass through them and save the electrician from any electric shock.
