Across
  1. 4. Events or things we can observe but not yet completely explain
  2. 7. An example of an energy source
  3. 8. A circuit in which two or more components are arranged end to end to form only one connection to the source
  4. 10. The primary carrier of electricity; a particle with a negative charge
  5. 12. The amount of available resource
  6. 14. An adjective to describe a resource that is stable, predictable, and consistent
  7. 15. This type of circuit is created when energy transfers down the wrong path
  8. 17. A device or machine that converts mechanical energy to electrical energy
  9. 20. Describes resources that produce energy effectively with a minimum of waste, expense, or effort
  10. 21. Something that a plan or design needs to be successful
  11. 22. The amount of resource one is requiring
Down
  1. 1. This type of switch completes a second path so energy can transfer
  2. 2. Limitations on a design or plan
  3. 3. A type of lightbulb that transfers 85% of the energy it receives into light
  4. 5. The junction point between electricity generation and distribution; it gather electricity from various sources and distribute it to end users across a wide area
  5. 6. An electrical safety device that is destroyed during overload conditions; protects an electric circuit from excessive electric current
  6. 9. A type of material that does not conduct electricity well,often used in the wrapping of wires
  7. 11. A type of fossil fuel along with oil and natural gas
  8. 13. This type of circuit is created when there is no energy transfer due to a damage or disconnection of the second path
  9. 16. This wire gives electrical energy a safe place to go if there is excess electrical energy in other parts of the system
  10. 18. The type of energy associated with movement of electrons through a wire or circuit
  11. 19. A circuit in which two or more components are connected to the source with separate conducting paths
