Answer 3

The handles of many electrical appliances are made of rubber or plastic because these materials are poor conductors of electricity and provide thermal insulation. This means that they do not allow the electric current to flow through them and they prevent the heat generated by the appliance from reaching the user's hand. By using rubber or plastic handles, the user can avoid electric shocks and burns when handling these appliances. Some examples of electrical appliances with rubber or plastic handles are hairdryers, toasters, irons, kettles, etc.
