Across
  1. 2. usually plugged into the mains to supply electric current
  2. 4. controls the amount of current flowing
  3. 7. supplies the voltage to make current flow in a circuit,transfers its store of chemical energy to electrical energy
  4. 9. plugged into the mains, supplies alternating current
  5. 10. transfers electrical energy to movement
  6. 11. transfers kinetic energy to electrical energy
Down
  1. 1. resistance can be varied to control current
  2. 3. can be open to stop current flowing or closed to allow current to flow
  3. 5. more than one cell working together to increase the voltage or the time in the current can be delivered for
  4. 6. transfers electric energy to heat energy
  5. 8. transfers electrical energy to light and heat
