Question

The handles of tools like screwdrivers and plieres used by electrician for repair work usually have plastics or rubber covers on them. Can you explain, why​

Answer 1

Answer:

plastic helps in person by heating safety,in screw drivers ,we can't get shock, plastic is a poor conductor of electricity so we can t get shock, plastic is insulator which is safety at electrical appliances

Answer 2

the handles of such tools are made of rubber, wood etc. because the are Insulators(materials which do not catch electricity). And our human body is a great conductor of electricity(materials which easily catches electricity) and if there will be metal handles then while doing an electric work, the tool can accidentally catch electricity which will flow in the workers body.. and the worker can be harmed so to prevent such circumstances rubber or plastic covers are made.

hope it helped
