Which statement explains the role of the paperclip in the circuit?

• The paper clip is an insulator that absorbs the flow of electrical energy.

• The paper clip is a conductor that prohibits the flow of electrical energy.

• The paper clip is an insulator that allows the flow of electrical energy

• The paper clip is a conductor that allows electric energy to flow through.

A student slides down a plastic slide on the playground. It is very warm but does not burn like a metal slide because-

• Plastic is a good conductor

• Plastic is a poor insulator

• Plastic is a good insulator

• Plastic is an expensive material
