  3. Main Board $100 Answer from krAMPus • Static

  4. Main Board • Answer $200 Question from krAMPus • What unit is used to measure current (Shortened and Long Version)?

  5. Main Board $200 Answer from krAMPus • Amps or Amperes

  6. Main Board • Answer $300 Question from krAMPus • When Current ____, Voltage ___ • When Voltage ___ , Current ___

  7. Main Board $300 Answer from krAMPus • When Current ▲, Voltage ▲When Voltage ▼ , Current ▼

  8. Main Board • Answer $400 Question from krAMPus • When current can pass through both a thin wire and a thicker wire, which would have less resistance? Why?

  9. Main Board $400 Answer from krAMPus • Big wire, means the larger space, the more current we can have

  11. Main Board $500 Answer from krAMPus • When Amperage increases then Resistance decreasesand Vice Versa

  12. Main Board • Answer $100 Question from Voltlander 2 • The unit of measure for Voltage is _____________ 

  13. Main Board $100 Answer from Voltlander 2 • Volts

  14. Main Board • Answer $200 Question from Voltlander 2 • An Electric Circuit must be __________ to work.

  15. Main Board $200 Answer from Voltlander 2 • Complete

  16. Main Board • Answer $300 Question from Voltlander 2 • A ______________ is required for Voltage to carry a current in a circuit.

  17. Main Board $300 Answer from Voltlander 2 • Voltage Source

  18. Main Board • Answer $400 Question from Voltlander 2 • How is Voltage SIMILAR to a rollercoaster?

  19. Main Board $400 Answer from Voltlander 2 • High potential energy from the top, lower as it goes down - Electricity has high potential at the Power Plant, moves away from high concentration

  20. Main Board • Answer $500 Question from Voltlander 2

  21. Main Board $500 Answer from Voltlander 2 • A. 12 Volts for both • B. 4 Ohms and 1 Ohms • C. 3 amps and 6 amps on each branch or 12 total

  22. Main Board • Answer $100 Question from Daddy's Ohm • This is the unit of measure for Resistance, and it's Symbol.

  23. Main Board $100 Answer from Daddy's Ohm • Ohm’s and Ω

  24. Main Board • Answer $200 Question from Daddy's Ohm • Something with a ___________ resistance will not allow charges to flow easily.

  25. Main Board $200 Answer from Daddy's Ohm • High

  26. Main Board • Answer $300 Question from Daddy's Ohm • A lemon with zinc and iron sticking out of it is a _______________. • Identify the Electrodes and the Electrolyte.

  27. Main Board $300 Answer from Daddy's Ohm • Battery • Electrode –Zinc and Iron • Electrolyte – Lemon Juice

  28. Main Board • Answer $400 Question from Daddy's Ohm • After a long day at school, you finally get to sit home and relax. You turn on your 120 Volt Nintendo that uses a current of 10 amps and your television that has a potential difference of 42, with 0.5 amps. Suddenly, you realize your living room circuit breaker will power off if you have more than 95 Ohms of resistance. • Will your Circuit breaker power off? Why or why not?

  29. Main Board $400 Answer from Daddy's Ohm • 120 V/10 A = 12 Ω Nintendo • 42 V/0.5 A = 84Ω TV • 96 Ω Total. • Yes it will turn off, too much resistance!

  30. Main Board • Answer $500 Question from Daddy's Ohm • Give all 4 factors that affect resistance and explain how.

  31. Main Board $500 Answer from Daddy's Ohm • Length – Longer more Ω, shorter less • Diameter – Thinner more Ω, Thicker less • Material it is made from – Insulator vs Conductor • Temperature – Heat means Ω, Cool is better

  32. Main Board • Answer $100 Question from Star Watts Episode VII • This is the formula to determine power

  33. Main Board $100 Answer from Star Watts Episode VII • Power = Volts x Amps

  34. Main Board • Answer $200 Question from Star Watts Episode VII • Draw the circle that will help Solve for power, and the three formulas associated with it

  35. Main Board $200 Answer from Star Watts Episode VII • Power= Volts X AmpsAmps = Power/ VoltsVolts = Power/Amps

  36. Main Board • Answer $300 Question from Star Watts Episode VII • The difference between • a wet cell and a dry cell

  37. Main Board $300 Answer from Star Watts Episode VII • Wet cell electrolyte is a liquid • Dry cell electrolyte is a paste

  38. Main Board • Answer $400 Question from Star Watts Episode VII • Lemon juice is an example of a(n) ________

  39. Main Board $400 Answer from Star Watts Episode VII • Electrolyte

  40. Main Board • Answer $500 Question from Star Watts Episode VII • What is the total resistance of the circuit?

  41. Main Board $500 Answer from Star Watts Episode VII • 26W/10V = 2.6A • 14W/10V=1.4A • 94W/10V=9.4A • 10V/2.6A=3.85Ω • 10V/1.4A=7.14 Ω • 10V/9.4A=1.06Ω • HOWEVER TOTAL Ω = TOTAL V / TOTAL A • 10V/13.4A = .75 Ω

  42. Main Board • Answer $100 Question from The Hunger Games: ElectricJay • Lightning is an example of this

  43. Main Board $100 Answer from The Hunger Games: ElectricJay • Induction

  44. Main Board • Answer $200 Question from The Hunger Games: ElectricJay • What is significant about Edison and Tesla’s rivalry? What are they known for today? (In relation to each other)

  45. Main Board $200 Answer from The Hunger Games: ElectricJay • Tesla worked for Edison, invented a better product but his name was slandered so he isn’t as famous as he probably should be. • Edison – Direct Current • Tesla – Alternating Current

  46. Main Board • Answer $300 Question from The Hunger Games: ElectricJay • How do direct and alternating current differ?

  47. Main Board $300 Answer from The Hunger Games: ElectricJay • Direct travels in one direction continuously, cant travel very far, mostly used for batteries now • Alternating current travels back and forth repeatedly, can be used over long distances, almost all electric now.

  48. Answer • Main Board $400 Question from The Hunger Games: ElectricJay • A 490 Watt Microwave uses 7.0 Amps of power from a wall socket. How much Resistance does the microwave have?

  49. Main Board $400 Answer from The Hunger Games: ElectricJay • 10 Ohms

  50. Answer • Main Board $500 Question from The Hunger Games: ElectricJay • A circuit contains a 12-volt battery and two 3-ohm bulbs in series. • Calculate the total resistance of the circuit. • Calculate the current in the circuit. • Calculate the power of each bulb. • Calculate the power supplied by the battery
