Across
  1. 5. have a negative charge
  2. 9. addition of light bulbs cause the rest to dim
  3. 10. current that reverses its direction regularly; generators use this
  4. 12. a coil of wire acting as a magnet when carrying electric current
  5. 13. converts electricity into mechanical energy
  6. 15. converts mechanical energy into electrical energy
  7. 16. a pathway of conductive materials for the movement of charged particles to flow in current electricity
  8. 17. makes electric charges move
  9. 18. addition of light bulbs does not affect brightness
Down
  1. 1. unit for current
  2. 2. current that flows through a wire in only one direction; batteries use this
  3. 3. the degree to which the flow of electrons is restricted
  4. 4. movement of electrons through a conductor
  5. 6. a material that does not allow electrons to move through it easily
  6. 7. a solenoid wrapped around an iron core
  7. 8. production of voltage due to a change in the magnetic field
  8. 11. unit for resistance
  9. 14. a material that allows electrons to move through it easily
