1. What is Current Electricity?

2. Current Electricity: the flow of electrons along a pathway (wire) from negative to positive.

3. Circuit: (from the root word circle) A pathway for electrons that ends at the same point it starts.
Negative

4. Complete or Closed Circuit: A circuit in which electrons can flow and complete the path from the negative to the positive terminal of the battery.
Negative

5. Incomplete or Open Circuit: A circuit in which electrons cannot flow and therefore cannot complete the path between the negative and positive terminals of the battery because of openings or breaks.

6. Incomplete or Open Circuit

7. Electrical Device: any item used in an electric circuit.

8. A. Load:(L) An electrical device that uses or resists electricity.

9. B. Non-Load:(NL) An electrical device that does not use electricity and does not have any resistance.

10. 1. Safety Devices: (SD) a non-load electrical device that controls the circuit.

11. 2. Power Supplies: (PS) a non-load electrical device that supplies power to the circuit.
