Electricity and Circuits


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? 


Rubber and plastic are bad conductors of electricity. It does not allow current to flow through it. Hence, handles of tools such as screwdrivers which are used by electricians usually have plastic or rubber cover on them. This protects them from electric shocks.
