Answer:
a. because if we does not remove the coating electricity cannot pass through it
b. to check the earthing of a socket we need to put the screwdriver or tester. It has plastic or rubber coating because if we put it directly we can get severe shock. The plastic or the rubber acts as an insulator to stop the flow of current from the socket to our body.
