Chapter 24, Problem 8STP

To determine

To Choose: The correct option.

Explanation of Solution

Introduction:

An electrical wire is a good conductor of electricity. A polymer coating on the wire should be a bad conductor of electricity.

An electrical wire uses a polymer coating to prevent current from flowing into another conductor. For example: If a person accidentally touches an electrical wire that is not coated with a polymer, he will receive an electric shock. On the other hand, if the wire is coated with a polymer, the polymer will prevent the flow of electricity from the wire to the person.

Conclusion:

The polymer coating on the wire should have high resistivity. Option D is correct.
