Answer 1

An insulator is applied around copper wires to keep the electric current confined to the conductor so it doesn’t touch other conductors or metal parts and create short circuits. It also protects people from electric shock and helps prevent physical damage and corrosion to the wire, maintaining circuit reliability.
