Across
  1. 2. two circuits linked by magnetism
  2. 4. melts when current gets too high
  3. 5. mA
  4. 12. diagram that shows the direction that a positive charge would move
  5. 15. a number of cells connected in series
  6. 16. voltage across a particular component
  7. 20. energy transferred per unit charge
  8. 22. having no charge
  9. 23. must be connected in series
  10. 25. resistor that always has a directly proportional current voltage relationship
  11. 26. -1.6 x 10(-19)
  12. 27. joules ÷ seconds
  13. 28. combining resistors this way results in a lower resistance than the sum of resistances
  14. 29. only allows current to flow in one direction
Down
  1. 1. current that flows in two directions
  2. 2. like charges
  3. 3. increasing this increases resistance
  4. 6. voltage x current
  5. 7. decreasing this, increases resistance
  6. 8. electricity is paid for in
  7. 9. voltage ÷ current
  8. 10. resistance decreases with increasing temperature
  9. 11. turns kinetic energy into electrical energy
  10. 13. an appliance with a metal case must have this
  11. 14. MV
  12. 17. basic safety feature on electrical cables
  13. 18. lead reindeer
  14. 19. current x time
  15. 21. opposite to electron flow
  16. 24. relay that turns off circuit if current is too high
