  1. 3. A device that stores and produces electricity from chemical cells.
  2. 5. A device that can be used to measure current, voltage and resistance in circuits.
  3. 9. The build up of an electric charge on the surface of an object.
  4. 13. An electrical circuit that is not complete. Often a switch is used to "open" the circuit so that current no longer flows.
  5. 14. Neutron subatomic particle found in the nucleus of the atom.
  6. 17. A substance or device that does not allow electricity to flow.
  7. 18. SI unit for electric potential
Down
  1. 1. A complete unbroken circuit around which current flows.
  2. 2. SI unit of electric charge
  3. 4. A form of energy resulting from the existence of charged particles.
  4. 6. The ability to do work.
  5. 7. The standard unit of measure used for electric power
  6. 8. Positively charged particle found in the nucleus of the atom.
  7. 9. A circuit with an often unintended contact of components allowing current to bypass resistors/lamps, etc.
  8. 10. SI unit of current flow
  9. 11. The movement or flow of electrons through a conductor.
  10. 12. A negatively charged particle that orbits the nucleus of an atom.
  11. 15. SI unit of resistance
  12. 16. A material or device that allows electricity to flow.
