Across
  1. 3. a unit of measurement of the electrical potential difference between two points.
  2. 5. Circuit an arrangement of the components of a circuit so that all positive terminals are connected to one point and all negative terminals connected to a second point, the same voltage being applied to each component.
  3. 6. a safety device that melts when current is too high, breaking the circuit (non-resettable/non-reusable)
  4. 9. an area around a magnet where force can be felt.
  5. 11. a safety device that trips when current is too high, breaking the circuit (resettable)
  6. 14. A temporary magnet made by passing an electric current through a wire coiled around an iron bar.
  7. 15. a particle in the space outside the nucleus of an atom that carries one unit of negative electric charge
  8. 16. Circuit an end to end arrangement of the components so that the same current flows through each component.
  9. 19. the flow of electric charges
  10. 20. a measure of how difficult it is for an electric current to flow through a material
  11. 21. Current an electric current that flows in one direction only
  12. 23. cycles/second, 1 Hertz=1 cycle/second, US: 60Hz, Europe: 50Hz
  13. 24. unit of measure for current
Down
  1. 1. Circuit a broken path that does NOT allow energy or electricity to flow
  2. 2. Current an electric current that reverses its direction at regular intervals
  3. 4. A machine used to generate power in which a wheel with blades spin, pushed by water, steam, wind, etc.
  4. 7. a magnet that keeps or retains its magnetism after the energy source has been removed
  5. 8. Current The flow of electrons from a negatively charged object to a positively charged object.
  6. 10. Circuit The path along which electrons flow
  7. 12. Circuit a closed path that allows energy or electricity to flow
  8. 13. Watt is the unit of electric power. One watt is defined as energy consumption rate of one joule per second. Watts=voltage x amps
  9. 17. an electrical component that can break an electrical circuit
  10. 18. Wire A wire, usually copper or aluminum that is enameled with an insulative material for the windings of electrical equipment.
  11. 22. substance that prevents electricity from passing through
