electricity vocab

4. Current (AC) Electric current that repeatedly reverses direction.
9. Current Net movement of electric charges in a single direction
10. Field: Surrounds every electric charge and exerts the force that causes other electric charges to be attracted or repelled
12. Difference The force that causes electric charges to flow
13. The tendency for a material to resist the flow of electrons and to convert electrical energy into other forms
15. Current (DC) A flow of charge that always flows in one direction.

1. A material through which electrons move easily
2. The flow of 1 coulomb of charge per second.
3. Circuit-- Devices in which a circuit forms branches, each of which is a separate path for electron flow
5. A material in which electrons are not able to move easily
6. An electronic device that allows electron flow in only one direction.
7. Source An object that provides a potential difference
8. Circuit- Devices in a circuit form a single pathway for electron flow
11. of Conservation of Charge: Charge can be transferred from object to object, but it cannot be created or destroyed
14. A complete pathway that allows the flow of electrons
