Across
- 2. A flow of electricity.
- 3. A given quantity of electricity.
- 4. Provides more than one path for electricity to flow.
- 5. Consists of a battery (power source), wire (conductor), an electric device (load) and switch (control) connected together to form a closed circuit.
- 6. An incomplete path, electricity cannot cross the break in the circuit.
- 8. Anything that uses electricity or batteries.
- 16. Unit used to measure power.
- 20. The point on the battery where electrons leave.
- 21. Contains positive and negative electrodes surrounded by an electrolyte. A chemical reaction occurs within the cell which generates electricity (releases electrons). One or more cells connected together is called a batter.
- 22. A device used for generating electricity through a electrochemical reaction; a battery unit it made from one or more cells
- 23. A device used to control the flow of electricity
Down
- 1. One path (loop) for electricity through all loads. If one bulb or battery is disconnected, the circuit will not work.
- 4. The point on the battery where electrons enter.
- 7. An electrical component, which slows electron flow.
- 9. Places (on bells, bulbs and other electrical divided) where wires are connected to allow for the flow of electricity.
- 10. Anything an electrical current can pass through easily
- 11. A type of energy in which small particles (called electrons) move through a device.
- 12. Materials that electricity has a hard time flowing through; e.g. plastic coating on wire, leather, wood, etc.
- 13. The capacity for doing work; may be electrical, mechanical, chemical, thermal or nuclear.
- 14. A complete path for an electric current.
- 15. Where the current flows from the battery through an electrical device providing power, and returning back to the battery.
- 17. A measure of the amount of electrical energy supplied to each charge.
- 18. An electrical device.
- 19. A very fine wire.
