Across
- 1. The unit of measurement of the electrical resistance of a material.
- 5. An electrical connection to the earth.
- 6. An electrical component used for connecting, breaking, or changing the connections in an electrical circuit.
- 12. A power system's layout of its substations and power lines.
- 15. The resistance to flow of electricity through a material.
- 19. The path followed by a flow of electric current.
- 20. A negatively charged particle that orbits the nucleus of an atom. The flow of electrons produces electricity.

- 16. An opening into which something fits, such as a light socket.
- 17. A unit for measuring electrical energy. (demand)
- 18. The unit of measurement of force used to produce an electric current.
- 21. Field An identified force that exists around a magnet or electrical field.
- 22. A large fan(s) that is coupled to a generator field. This turbine (fan) is put into motion by the force of water, steam, or hot exhaust gases that rotate the turbine.
- 23. Hour One kilowatt of electrical energy produced or used in one hour. (energy)
- 25. Measurement of current flow through a conductor.
- 30. A short duration of increased voltage.
