Question

Plastic is used to cover electrical cords. This indicates that plastic is a(n) ________.
A. conductor
B. plasma
C. form of energy
D. insulator

Answer 1

It wouldn't be a conductor because that would be foolish of engineers to wrap electricity with something that will -conduct- or even amplify the electrical current when you touch it. The answer is D. It insulates the electric cords thus removing a good chance of killing yourself (depending on the appliance, et cetera.)

Answer 2

D insulator is the right answer

Answer 3

Some common insulator materials are glass, plastic, rubber, air, and wood.
Most metals are considered to be good conductors of electrical current.
So the plastic on an electrical cord is an insulator D

Answer 4
