Across
  1. 5. the charge of how the energy is supplied to your home.

  3. 8. a device that is operated electrically e.g. a kettle.
  4. 9. a material that does not let energy flow through it easily.
  5. 10. to rise up.
  6. 12. a material or energy source that will not run out.
  7. 13. the amount of power used per hour.
  8. 15. the build up of electrical charge within or on the surface of an insulated object.
  9. 18. a tiny particle that forms the central nucleus of an atom.
  10. 19. the ends of a magnet – north pole and south pole.
  11. 20. the space around a magnet where it can affect magnetic materials or other magnets.
  12. 21. the number of joules of energy an appliance transfers every second.
  13. 23. a coil of wire.
  14. 24. the amount of energy transferred by each unit of charge passing between two points of a circuit.
  15. 26. information/data that can take any value, such as speed, so these values don’t need to be whole numbers.
  16. 29. the centre of an atom which consists of protons and neutrons.
  17. 30. the transfer of heat energy by waves.
  18. 33. a region where charges experience a force.
  19. 34. what flows in an electric current when a battery is connected within the circuit.
  20. 35. a factor which can change or be changed in an experiment.
  21. 36. materials that conduct heat or electricity poorly.
  22. 37. the smallest part of an element.
  23. 38. a way of saying how difficult it is for electricity to flow through something.
  24. 39. a material that lets energy flow through it easily.
  25. 42. a component that measures voltage.
  26. 44. a piece of equipment that measures how much electricity is flowing around a circuit.
Down
  1. 1. the amount of steady current through a large number of materials is directly proportional to the voltage across the materials and inversely proportional to the resistance.
  2. 2. the transfer of heat in fluids.
  3. 3. the iron part of a relay that moves when electricity is flowing in the solenoid (or electromagnet).
  4. 4. any energy resource that will run out and we cannot renew our supplies of it (e.g. oil).
  5. 6. a force, such as magnetism or gravity, that does not need to be touching something to have an effect.
  6. 11. a coil of wire with electricity flowing in it. An electromagnet has a magnetic field like a bar magnet.
  7. 14. the amount you pay for every unit of energy you use, measured in kWh.
  8. 16. push away.
  9. 17. a circuit where there is only one loop of wire.
  10. 22. tiny particle that flows around a circuit.
  11. 24. the action of pushing forwards.
  12. 25. the way heat travels through solids.
  13. 27. a resistor that can be adjusted to change the amount of resistance it has.
  14. 28. a way of saying how much energy is transferred by electricity.
  15. 31. if an investigation is repeated by another person or by using different equipment, the same results are obtained.
  16. 32. the flow of electrons around a circuit
  17. 40. a tiny particle found in the nucleus of an atom, with a positive charge.
  18. 41. two things pulling towards each other.
  19. 43. a magnetized piece of metal that can swing around – it points north.
  20. 45. giving a material magnetic properties.
