Across
  1. 3. Unit of current. The charge that flows during one second
  2. 5. Unit of electric charge
  3. 8. A component made of a thin wire that protects a circuit from electrical fire. If the current gets too large, the fuse wire melts (the fuse 'blows') and stops the current.
  4. 14. A Component which changes electrical energy into light energy
  5. 15. unit of power
  6. 16. A material with high resistance and that doesn’t let electricity pass through
  7. 17. Used in a circuit when there is more than one cell
  8. 18. a material that always lets electrical current to pass through
  9. 20. A piece that only lets electricity flow in one direction
  10. 21. Describes a circuit in which the current travels along one path through every component.
  11. 22. A component in a circuit. When closed the current can flow. When open the current cannot flow.
Down
  1. 1. the unit of resistance
  2. 2. A meter that is used to measure the voltage of a circuit
  3. 4. Describes a circuit in which the current splits up into more than one path.
  4. 6. Flow of electric charge. Measured in Amps. The number of coulombs of charge that flow per second.
  5. 7. A very thin piece of wire inside a lamp that glows and gets hot when current passes through it
  6. 9. A component which changes chemical potential energy to electrical energy.
  7. 10. The measurement of how hard it is for electricity to pass through a wire
  8. 11. an electrical device that has a specific definition
  9. 12. the flow in a circuit that makes a current
  10. 13. amount of energy transferred every second
  11. 19. current current that only flows in only one direction
  12. 23. something that changes chemical potential energy into electrical energy
