  1. 3. Law describes the way current flows through a resistance when a different electric potential (voltage) is applied at each end of the resistance.
  2. 4. a device that converts mechanical energy to electrical energy
  3. 7. the sound made by a flash of lightning
  4. 8. positively charged particles found in the nucleus of an atom
  5. 10. current the constant flow of electric charge in one direction
  6. 12. a backup pathway that provides an alternating route for the current to flow back to the ground if there is a fault in the wiring system
  7. 14. Negatively charged particles that are found outside the nucleus
  8. 15. cell battery a device made of one or more electrochemical cells that convert stored chemical energy into electrical energy. It contains an electrolyte that is contained within a paste or other moist medium.

  1. 1. involves the contact of a charged object to a neutral object.
  2. 2. circuit A circuit that has a break in its path, will not work
  3. 5. potential difference in charge between two points in an electrical field
  4. 6. A path along which electric charges can flow
  5. 9. an object, substance or material allowing the flow of an electric charge
  6. 11. breaker an automatic device for stopping the flow of current in an electric circuit as a safety measure
  7. 13. charging a method used to charge an object without actually touching the object to any other charged object
  8. 16. measure of the opposition to current flow in an electrical circuit
  9. 18. Current current where the flow of electric charge is constantly changing directions
  10. 20. circuit A circuit that does not have a break in its path, will work
  11. 21. a material whose internal electric charges do not flow freely; very little electric current will flow through
  12. 23. type of magnet in which the magnetic field is produced by the flow of electric current.
