2. Unit of measurement for electrical energy.
6. Circuit The electrical current has only one pathway through the circuit.
9. A type of electrical current where electrons move backwards and forwards, produced by power stations.

1. A type of electrical current where electrons move only in ONE direction, produced by batteries.
3. A measure of how difficult it is for electrons to flow through a circuit.
4. Object with a very large electrical resistance, does not allow electrical current to flow.
5. A measure of the amount of electrical energy gained or lost by and electric charge as it moves through a circuit.
7. Circuit The electrical current has more than one path through the circuit.
8. Object with very little electrical resistance, and allow a large amount of electrical current to flow.
10. Used in electrical circuits to control/vary the flow of electrical current.
