Copper wire- conductor
Rubber - insulator

4. Conductors
Conductor Examples: coin, metal paperclip, silver, gold, iron, brass, graphite (pencil lead), aluminum can and copper wire
Copper is considered to be a conductor because it “conducts” the electron current or flow of electrons fairly easily. Most metals are considered to be good conductors of electrical current.
In a conductor, electric current can flow freely.

5. Insulators
Insulator Examples: plastic, paper, dry wood, rulers, glass, cotton and rubber
Insulators are used to protect us from the dangerous effects of electricity flowing through conductors.
In an insulator the electric current cannot flow freely.
