Which of the following reasons explains why electrical cords are plastic coatings with metal wires on the inside? A.Both plastic
and metal have high electrical conductivity. B.Both plastic and metal have low electrical conductivity. C.Plastic has high electrical conductivity, and metal has low electrical conductivity. D.Plastic has low electrical conductivity, and metal has high electrical conductivity
The answer is D because, and because of the fact that plastic has low electrical conductivity, makes the electrical cord safe to handle when in use. It's like a barrier between whatever the cord is touching, and the wires inside.
