Across
  1. 4. The number of joules of energy an appliance transfers every second.
  2. 5. A fuel made from plants or from animal droppings.
  3. 7. Electricity at 230 V provided to houses, shops, etc.
  4. 8. A way of saying how much electrical energy is available.
  5. 9. The flow of electrons around a circuit.
  6. 11. System of overhead and underground cables that carry electricity around the country.
  7. 12. The unit for measuring power.
  8. 13. A component that makes it more difficult for current to flow.
  9. 15. The label on an appliance that tells us how much electrical power it transfers.
  10. 17. Electricity made when falling water (usually from a reservoir) turns turbines and generators.
  11. 18. The unit for measuring current.
  12. 19. Equipment that measures how much current is flowing around a circuit.
