which best describes the materials that make up an electrical cord?\no a metallic conductor lacking free electrons surrounded by a rubber insulator with free electrons\no a metallic conductor with free electrons surrounded by a rubber insulator lacking free electrons\no a metallic insulator with free electrons surrounded by a rubber conductor lacking free electrons\no a metallic insulator lacking free electrons surrounded by a rubber conductor with free electrons
Answer
Brief Explanations:
Conductors have free - moving electrons to carry electric current, like metals. Insulators do not have free - moving electrons and prevent current from flowing through them, like rubber. An electrical cord has a metal conductor to carry electricity and a rubber insulator to prevent shock and short - circuits.
Answer:
a metallic conductor with free electrons surrounded by a rubber insulator lacking free electrons
