which best describes the materials that make up an electrical cord?\n a metallic conductor lacking free electrons surrounded by a rubber insulator with free electrons\n a metallic conductor with free electrons surrounded by a rubber insulator lacking free electrons\n a metallic insulator with free electrons surrounded by a rubber conductor lacking free electrons\n a metallic insulator lacking free electrons surrounded by a rubber conductor with free electrons

which best describes the materials that make up an electrical cord?\n a metallic conductor lacking free electrons surrounded by a rubber insulator with free electrons\n a metallic conductor with free electrons surrounded by a rubber insulator lacking free electrons\n a metallic insulator with free electrons surrounded by a rubber conductor lacking free electrons\n 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, and insulators do not. Electrical cords have a metallic conductor (like copper) with free electrons to conduct electricity and a rubber insulator (which lacks free electrons) to prevent electric shock and short - circuits.

Answer:

a metallic conductor with free electrons surrounded by a rubber insulator lacking free electrons
