question_answer 16)

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?

Answer:

As we know that human body is a good conductor of electricity. So, it is necessary to prevent it from electric shocks. On the other hand, plastic and rubber are insulators that do not allow electricity to pass through them. Hence, electricians use screwdrivers and pliers which have plastic or rubber covering on them for repair work.
