soo.....if an electrician uses a screwdriver while fixing electric objects with a metal handle its sure that he gets an electric-shock .so the handles are made up of wood or plastic as they aint metals

Answer 2

As the screw driver is made of metal and all metals conduct electricity.Our body too is a conductor and the electrician may get a current shock.That is why to insulate and to avoid skin contact directly with the metal it has a plastic or wooden handle.
