3. This sub-atomic particle is transferred allowing an object to become negatively or positively charged.

4. Electrons

5. Open or Closed? Series or Parallel?

6. Open Series

7. How does an object become positively charged?

8. Loses Electrons

9. What 3 factors effect the amount of electrical resistance an object will have?

10. Temperature Diameter (width) Length

11. Working or non-working series?

12. Non-working (not all conductors/wires are connected to the battery/voltage difference.

13. This type of material allows the flow of electrons or transfer of heat.

14. A conductor.

15. Pulling off a wool hat or shuffling across the carpet creates _________ electricity.

16. Static

17. These 2 factors effect the amount of electrical force between objects.

18. Magnitude & distance

19. A resister transforms electrical energy into what 2 types of energy?

20. Heat (thermal) and Light (radiant)

21. Open or Closed? Series or Parallel?

22. Closed series

23. This type of circuit is used in houses and other buildings are wired so if something goes out, the rest of the building/house remains on.

24. Parallel circuit

25. What’s missing in the diagram? What’s missing in the diagram?

26. Pylon

27. This part of a light bulb acts as a resistor.

28. The filament. (tungsten metal)

29. Open or closed Series or Parallel

30. Open series circuit.

31. This item would provide a voltage difference in a circuit.

32. A battery An outlet A Generator

33. Excess electrons cause _________ electricity.

34. Static

35. Electric current flows in this direction.

36. Negative to positive. - to +

37. Wire acts as a _________ in an electric circuit.

38. Conductor

39. The diagram below displays this type of circuit. Open or Closed Series or Parallel

40. Closed parallel

41. This would occur when a large voltage and a small resistor causes too much current to flow.

42. A short circuit (blown fuse or popped breaker)

43. Open or Closed? Series or Parallel?

44. Open parallel

45. According to Ohm’s Law, when you increase a voltage difference or decrease the resistance, this action would occur.

46. An increase in electric current.

47. Series or Parallel? Open or Closed?

48. Closed Parallel

49. Series or Parallel? Open or Closed?

50. Closed Series

51. How is the balloon sticking to the paper?

52. The electrons have moved from the paper surface to the balloon surface causing a positive and negative electrical attractions.

53. Series or Parallel? Open or Closed?

54. Closed Series

55. How did the metal in the 3 rd picture change its charge?

56. The electrons moved from the rag to the metal leaving more positive protons behind and transferring electrons to the metal.

57. Series or Parallel? Open or Closed?

58. Closed Parallel

59. Working or non-working parallel?

60. Non-working because both resistors are not wired to the voltage difference.

61. Tell 2 reasons why the bulbs in the first circuit is brighter than in the second circuit. Circuit #1 Circuit #2

62. The series circuit has more resistance than the parallel. And/or There is less electrical energy for the second bulb to use on a series circuit.

63. Open or Closed? Series or Parallel?

64. Closed Series

65. Open or Closed? Series or Parallel?

66. Closed Parallel

67. GREAT JOB!!!!

68. Test Tomorrow!! Test is NOT open note!
