  1. 2. condition of the air/environment when static cling occurs the easiest/most
  2. 5. used to control the flow of electricity through a circuit; opens or closes gaps
  3. 7. charge-storage device used before capacitors; glass jar lined and coated with lead
  4. 8. type of electricity that requires a constant flow of electrons
  5. 10. particles formed from induction that have opposite charges at each end
  6. 14. When current bypasses a load a _?_ circuit can cause a fire.
  7. 16. metal pole attached to the top of tall buildings with a wire that reaches the ground; used to divert electrical discharges
  8. 17. what like charges do
  9. 18. A test charge approaching an object with a _?_ charge would attract.
  10. 21. can serve as conductors or insulators but not ideal as either
  11. 23. type of current that flows in only one direction; used in batteries and many portable electronics
  12. 24. process of temporarily charging part of an object without actually adding or removing electrons
  13. 25. a complete path from an electron source, through a conductor, and back
Down
  1. 1. type of circuit where if one bulb goes out, the others stay lit
  2. 3. The ability of something to impede, or slow the flow of charges is electrical _?_.
  3. 4. what opposite charges do
  4. 6. have tightly held electrons that limit their flow; ex: plastic, rubber
  5. 9. the very strong field force exerted by electrical charges
  6. 11. instrument that detects charge by separating its metal leaves
  7. 12. only atomic particles that affect electrical charge; these must be gained or lost
  8. 13. name for the objects in a circuit being powered by electricity
  9. 15. type of circuit where if one bulb goes out, the others go out too
  10. 19. loss of static charge
  11. 20. A test charge is always _?_ charged.
  12. 21. type of electricity that uses stationary or short, quick discharges
  13. 22. The electron _?_ theory states that charges flow from areas of high electron concentration to low.
