Answer:
The material should be conductor insulated by insulator
Explanation:
An electrical cord is an electrical cable that temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The most frequently used material for the conductor in an electrical cable is copper because it is the best conductor for the flow of electric current as it is abundant in free electrons. After that an insulator like rubber or plastic is placed between the two electrodes and then connected to an electrical socket.
