Question

An electrician wraps rubber electrical tape around a copper wire. Since rubber is an insulator, which statement best explains the point of wrapping rubber around a copper wire?

Answer 1

A) Rubber stops charges from flowing. This protects people by stopping electricity from flowing.

Explanation:

The statement that best describes the point of wrapping rubber around the copper wire is that the rubber stops charges from flowing. This prevents people from getting electrical shocks by stopping the flow  of electricity.

• A rubber is an insulator.
• Insulators are substances that prevents the flow of electricity.
• The lack free mobile electrons or ions that makes them conductors.
• When they are wrapped round a conductor such as copper wire, they will halt the flow of charges.
• Copper is a conductor of both heat and electricity. It has free mobile electrons.
