The plastic covering on wires is there to:

• Provide a conductor for electrical energy to flow.

• Provide an insulator so that electrical energy will not pass outside of the wires.

• Provide a conductor so that electrical energy can NOT flow.

• Provide an insulator so that electrical energy can flow.

What is the primary role of an insulator in an electrical circuit?

• To increase the flow of electricity

• To decrease the circuit's resistance

• To prevent the loss of heat

• To prevent the flow of electricity where it's not wanted

Answer explanation
