Which of the following materials do you think it would be safe to wrap the outside of a switch in?

Fill in the blank: A material that does not allow electricity to flow through it easily is called an electrical .

Looking at the diagram below, how do we know that the metal nail is a conductor?

I have used a plastic spoon in this circuit. Is the plastic spoon a conductor?

Metals tend to be good conductors while plastics are very good insulators. Look at the diagram of the wire shown and fill in the missing label with a material.
