Across
  1. 3. Allow electron flow- copper, aluminum
  2. 7. Charge of a proton
  3. 8. Only occurs with negative charges
  4. 10. Electron flow when two objects touch
  5. 13. Like charges repel, opposites attract
  6. 16. Force fields, can cause induction
  7. 18. Total maximum difference between positive and negative ends of electron source
  8. 21. Pathway for electron movement
  9. 22. Also potential difference, force at which electrons travel
  10. 23. A space where air has been removed
  11. 24. Allow partial electron flow
  12. 27. All electrons flow in the same direction
  13. 29. The area beyond a valence band
  14. 30. Electrons flow one way, then flow in reverse
  15. 31. Quantity of electrons flowing
  16. 32. Unit for current
  17. 33. Converts chemical energy to electrical
  18. 35. Nonconducting materials- plastic, glass
  19. 36. Electron flow when one object is rubbed against another
Down
  1. 1. Electrical field acting on another without contact
  2. 2. Study of distribution of fixed charges
  3. 4. Force or strength of electron flow
  4. 5. Allow e- flow with no resistance- silver, gold
  5. 6. Linked to one another
  6. 8. Used to regulate the number of electrons available to produce xray photons
  7. 9. Electrons try to repel each other and maximize distance between them
  8. 11. Converts mechanical energy to electrical
  9. 12. Amount of opposition to current in a circuit
  10. 14. Force is directly proportional to product of magnitudes, inversely to the square of the distance between objects
  11. 15. Charge of an electron
  12. 17. Process of electron charges added or subtracted from an object
  13. 19. Neutral, positive and negative in equal distribution
  14. 20. Shell that determines chemical and electrical properties of an atom
  15. 25. Unit of resistance
  16. 26. Can result in ionization, occurs where curvature is sharpest
  17. 28. Each component has its own branch
  18. 34. One charge is greater than the other, results in light photons
