You plug in an extension cord and have to be very careful around the electrical outlet. However, you can handle the extension cord without worry of being shocked by the electrical charge. Which statement best explains why you can do this? (2 points)
Select one:

a. The cord is made of a combination of materials, which are good conductors of electricity. The combination of two conductors directs the flow of electricity away from you and down the cord.
b. The extension cord is made of plastic which only conducts electricity for a certain period of time. If you handle the cord, the electricity passes through it so fast that you are not in danger of being shocked.
c. The extension cord is made of copper wire, which is a good conductor of electricity; however, it is covered with plastic, an insulator, which does not allow the electrical current to flow to you.
d. The cord has a plastic cover, which is a good conductor of electricity so it carries the electrical current away from your hand, which is an insulator.
