  1. Chapter 6 Ohm’s Law, Work, Energy and Power

  2. V = ? V I = 4 Amps R = 4 Ohms 16 V

  3. V = ? V I = 2 Amps R = 4 Ohms 8 V

  4. V = ? V I = .2 Amps R = 5 Ohms 1 V

  5. V = ? V I = 4 mA R = 4 mOhms 16 uV

  6. V = ? V I = 14 Amps R = .5 Ohms 7 V

  7. I = 5 uA R = 4 MOhms V = ? V 20V

  8. V = ? V I = 3 mA R = 2 kΩ 6V

  9. V = ? V I = 5 nA R = 1.5 GΩ 7.5V

  10. V = ? V I = 5 A R = 1.5 Ω 7.5V

  11. V = 6 V I = 3 A R = ? Ω 2 Ohms

  12. V = 6 V I = 3 A R = ? KΩ .002 Kohms

  13. Random Video of the Day

  14. Now Use your Calculator See page 91 in book Do Example 6.2

  15. Using your Calculator V = 6 V I = ? A R = 3 Ω 2 Amps

  16. Using your Calculator V = 6 V I = ? mA R = 3 Ω 2000 mA

  17. Using your Calculator V = 10 mV I = 2 mA R = ? mΩ 5000 mOhms

  18. Using your Calculator V = 10 mV I = 2 mA R = ? Ω 5 Ohms

  19. Using your Calculator V = 10 mV I = 2 mA R = ? MΩ .000005 MOhms

  20. Using your Calculator V = 10 x 10-4V I = 2 mA R = ? MΩ .0000005 MOhm 5 x 10^-7 MOhm

  21. Using your Calculator V = 10 x 10-4V I = 2 x 10-3A R = ? MΩ .0000005 MOhm 5 x 10^-7 MOhm

  22. Work What is work? Motion must take place for work to take place Work takes place when electrical energy is converted to mechanical energy and vice versa What is the unit for work? Joule (J) (This is also the same unit for Energy) What about electrical work? (no motion involved?) 1 Joule = Energy required to raise 1 Coulomb of charge through a potential difference of 1 Volt

  23. Work What is the equation for work? W = Q * V Work = Charge * Voltage Joules = Coulombs * Volts

  24. Power What is Power? Power is how much work can be done in a specific amount of time (Like MPH) Units for Power is Watts (W) (Like MPH) W = Q * V

  25. Power Equation for Power Power = Work / Time (Like MPH) Power = Voltage * Current P = V * I

  26. Power See how Power also equals: P = V2/R P = I2 * R

  27. P = V * I P = V2/R Power P = I2 * R P = ? Watts I = 6 Amps V = 3 Volts P = 18 Watts

  28. P = V * I P = V2/R Power P = I2 * R P = 18 Watts I = 6 Amps V = 3 Volts R = ? Ω R = .5 Ohms

  29. P = V * I P = V2/R Power P = I2 * R P = ? Watts I = 5 Amps V = 50 Volts V = ? Volts R = 10 Ohms P = 250 Watts

  30. P = V * I P = V2/R Power P = I2 * R P = ? Watts V = 3 Volts R = 9 Ω P = 1 Watts

  31. P = V * I P = V2/R Power P = I2 * R P = 32 Watts R = 2 Ω I = ? A I = 4 Amps
