- 4. A wire that carries electricity back to the power source, completing the circuit.
- 5. A safe path for excess electricity to travel into the earth, helping prevent shock and equipment damage.
- 8. An electrical outlet where a plug is inserted to supply power to devices.
- 9. The force or pressure that pushes electrical current through a circuit.
- 14. The unit used to measure electrical resistance.
- 15. A device used to open or close an electrical circuit, turning power on or off.
- 16. A machine that produces electricity by converting mechanical energy into electrical energy.
- 17. A measure of electrical power, showing how much energy is being used. (Volts × Amps)
Down
- 1. A permanent electrical device, such as a light or ceiling fan, that is attached to a structure.
- 2. A material, usually metal, that allows electricity to flow easily.
- 3. A device that increases or decreases voltage in an electrical system.
- 6. A measurement of wire size; smaller gauge numbers indicate thicker wire.
- 7. The opposition to the flow of electrical current in a circuit.
- 10. A type of receptacle with two outlets in a single unit.
- 11. The amount of electrical current flowing through a circuit.
- 12. A safety device that shuts off power when it detects an unsafe electrical current, helping prevent electric shock.
