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