  1. Electric Jeopardy!

  2. Electric Jeopardy!

  3. Which subatomic particle has a negative charge? Neutron Proton Electron Quark

  4. Which subatomic particle has a negative charge? Neutron Proton Electron Quark

  5. When do charges repelor attract?

  6. Charges repelwhen they are alike (2 positive or 2 negative charges). Charges attractwhen they are opposite (1 positive and one negative).

  7. Describe what the picture below represents.

  8. It shows Electric Fields, a force that surrounds the charged particle.

  9. Correctly label the 4 parts of the atom in this diagram. 1 2 4 3

  10. Electron Proton Nucleus Neutron Back to Menu Final Jeopardy

  11. Transferring a charge just by touching another object is called…

  12. Conduction.

  13. What type of charge transfer does the picture show? Why does your hair get all frizzy? DAILY DOUBLE!

  14. This picture shows charge transfer through Friction. Electrons move from the balloon to your hair and repel one another.

  15. What is Static Discharge? Give an example.

  16. Static Discharge is the loss of static electricity from an object. An example of this is lightning.

  17. Describe how the last type of charge transfer works and give an example of when it is used.

  18. Induction is the movement of electrons caused by electric fields. This can be used to charge controllers and phones. Back to Menu Final Jeopardy

  19. How is Static electricity different from Current electricity?

  20. Static electricity does not flow.

  21. The difference in the Electric Potential between two places is called…

  22. Potential Difference or Voltage.

  23. How does a waterfall demonstrate Voltage?

  24. Like water, current flows from areas of high potential to areas of low potential. High EP Low EP

  25. Why is it that birds sitting on power lines are not zapped? There are 2 reasons.

  26. The birds have a higher resistance than the wire and they are not touching the ground or another wire. Back to Menu Final Jeopardy

  27. What is Ohm’s Law?

  28. Resistanceis equal to the voltagedivided by the current. R = V I

  29. What are the 2 types of circuits? What is the primary difference between them?

  30. The 2 types of circuits are Seriesand Parallel. The main difference is that Series has only 1 path for charge to take while Parallel has multiple.

  31. Which circuit has greater resistance? Which has brighter bulbs? Which will not be affected if one bulb burns out?

  32. The series circuit will have greater resistance. The parallel circuit will be brighter and unaffected by a bulb burning out.

  33. You are building a seriescircuit with 5 light bulbs. If the power supply provides 120 volts and there is a current of 24 amps, what is the resistanceof one bulb.

  34. R = V I R = 120V 24A R = 5Ω Since there are 5 light bulbs, the resistance of 1 bulb is 1Ω. Back to Menu Final Jeopardy

  35. Electric Potential depends on… a) Height b) Electric field c) Voltage

  36. Electric Potential depends on… a) Height b) Electric field c) Voltage

  37. Who first described the parts of the atom and what charges did he give them?

  38. Benjamin Franklin gave the parts a positive (proton), negative (electron), and neutral (neutron) charge.

  39. What is a circuit breaker and why is it important?

  40. A circuit breaker opens a circuit so current can no longer flow. This helps protect from fires and other electrical hazards.

  41. Name the 4 possible factors that can change the resistance of a wire and how you can adjust them to increase it.

  42. The resistance of a wire depends on… Thickness (thicker resists more) Length (longer resists more) Material (metal vs. plastic) Temperature (hotter resists more) Back to Menu Final Jeopardy

  43. 60 30 10 What is pictured below? Label the 2 types of parts. Find the voltage if there is a current of 12 amps and a resistance of 3 ohms. 1 2 2 2

  44. STOP

  45. This picture shows… A parallel circuit. It consists of (1) a battery and (2) resistors. The voltage (V = I x R) is 36V. 1 2 2 2 Back to Menu
