Across
  1. 2. Which state of matter has particles that are arranged in rows, they can only vibrate round fixed positions.
  2. 4. Anything within a circuit that reduces the flow of electricity around the circuit.
  3. 6. This component only allows current to flow through it in one direction.
  4. 7. What is missing from this equation, Potential difference = Resistance x _________?
  5. 9. This is the potential difference of mains electricity
  6. 13. Energy cannot be created or destroyed it can only be __________
  7. 15. This device increases the voltage, it can be found at the start of the national grid.
  8. 17. What is the name of the radiation that has the largest ionising power?
  9. 19. What is the charge of a proton?
  10. 23. The energy needed to increase 1Kg of material by 1degree celcius.
  11. 24. This component must be placed in series within the circuit.
  12. 25. What is the energy stored in a stretched spring?
  13. 26. The name of a quantity that is the mass in a given volume.
Down
  1. 1. What are the units for pressure?
  2. 2. The energy needed to complete a change of state in a substance.
  3. 3. This current changes rapidly from positive to negative and back again (it flipflops).
  4. 5. What is the charge of an element atom when it is not an ion?
  5. 8. This is what we call 'the movement of charge' around a circuit.
  6. 10. This component must be placed in parallel within the circut.
  7. 11. Which element has an atomic mass of 12 and an atomic number of 6
  8. 12. Which type of radiation is an electromagnetic wave?
  9. 14. An energy resource that is replenished (it won't run out), eg tidal / wind
  10. 16. What was the name of the atomic model put forward by JJ Thompson?
  11. 18. This is the energy supplied to the circuit.
  12. 20. Kg are the units for?
  13. 21. Which atomic particle has no charge?
  14. 22. What are the units for power?
