Across
  1. 2. the distance between two successive peaks.
  2. 6. the light that gel enhancements use.
  3. 7. any substance that easily allows the flow of electricity with little resistance.
  4. 9. a unit that measures the resistance of an electric circuit.
  5. 10. the movement of electrons from one atom to another along a conductor.
  6. 11. the unit that measures the number of electrons that flow through a complete electric circuit.
  7. 12. the flow of electricity in a complete circuit.
  8. 14. a resettable electrical safety device that automatically shuts off an electric current at the first indication of an overload or short circuit.
  9. 16. the unit that measure the pressure or force that pushes the flow of electrons forward through a complete electric circuit.
  10. 17. completes an electrical circuit and carries the current safely away.
