Question

Electrical cords are made up of two layers. The wire inside is made of metal. This is surrounded by a cover made of plastic or rubber. How do the wire and cover compare in their ability to conduct or insulate electricity? A. The wire is a conductor, and the cover is an insulator. B. The wire is an insulator, and the cover is a conductor. C. Both the wire and the cover are insulators. D. Both the wire and the cover are conductors.

Answer 1

Answer:

A

Explanation:

The correct answer would be that the wire is a conductor and the cover is an insulator.

The wire inside an electrical cord is made up of metals and metals are generally considered to be good conductors of heat and electricity. The cover which is made of plastic or rubber, however, are known to be poor conductor of electricity. Hence, the wire are considered to be conductors of electricity while the rubber covers act as insulators to protect users from getting electrocuted.

The correct option is A.
