1. Electric Circuit A path on which electrons move continuously is called an electric circuit.

2. Ampheres A unit measuring the energy available to push an electrical charge through a circuit.

3. Electric Current The electric current is produced by a power source, such as a battery or electric outlet.

4. Think: In an electric circuit, how does an electric current travel through the circuit?

5. Electrons move along a wire made of metal. The metal attracts the electrons and is called a conductor.

6. Surrounding the metal is a covering made of rubber or another protective material. This cover is keeping the electrons contained so they stay on the metal path. This covering is called an insulator.

7. Think: What will happen if the electric circuit is broken? Why?

8. Think: What are some things we use that need a closed circuit to work?

9. Think: Why is static electricity NOT a good source of energy? (power source)
