Intro To Electricity And Electronics

  1. 1. Intro to Electricity and Electronics<br />The Shocking Truth!<br />
  2. 2. Electrical Systems<br />PCM<br />BCM<br />Exterior Lights<br />Interior lights<br />Power accessories<br />Heated seats<br />Radio/ System<br />Navigation systm. <br />Starting<br />Charging<br />Backup Alert <br />GM - Onstar<br />Ford - Sync <br />Airbag systems<br />
  3. 3. What is electricity? <br />Electricity is the flow of electrons on the valance, outer, shell of an atom.<br />http://www.flickr.com/photos/argonne/3853255001/<br />
  4. 4. Two Types of Electricity?<br />Conventional Flow vs. Electron Flow<br />Conventional Theory: electricity flows from positive to negative<br />Electron Theory: Electricity flows from negative to positive<br />Blame it on Ben!<br />For our purpose: Electricity flows out of the positive terminal of the battery into the negative (ground). <br />
  5. 5. Conductors <br />Conductors have one to three electrons in their valance band.<br />Examples:<br />Platinum <br />Copper<br />Silver <br />Gold <br />
  6. 6. Insulators <br />Insulators have eight electrons in their valance band and do not conduct electricity well. <br />Plastic <br />Rubber<br />Porcelain <br />Wood<br />You<br />
  7. 7. Important Terms<br />Current: <br />The amount of electricity<br />Measured in amps<br />The water in the hose <br />http://farm1.static.flickr.com/57/193508636_cd6176a58f.jpg<br />
  8. 8. Important Terms<br />Voltage<br />The force or electrical pressure <br />The Push<br />http://farm3.static.flickr.com/2457/3555980548_0d21baff62_b.jpg/bmi_orig_img/3555980548_0d21baff62_b.jpg<br />
  9. 9. Important Terms<br />Resistance: <br />Opposition to current flow<br />Measured in Ohms<br />Your Thumb!<br />
  10. 10. Meet George <br />George Ohm<br />Born 1789<br />Published book in1827 on electricity <br />Loved to dance* <br />
  11. 11. http://en.wikipedia.org/wiki/File:Denkmal_Ohm_TU_M%C3%BCnchen.jpg<br />
  12. 12. Ohm’s Law<br />Resistance = Voltage divided by Current<br />Ohms = Volts/Amps <br />Volts = Amps x Ohms <br />Amps = Volts/Ohms<br />http://en.wikipedia.org/wiki/File:Omega_uc_lc.svg<br />
  13. 13. Example of Ohm’s Law<br />Automotive Battery Voltage = 12v <br />Resistance of light bulb = 2 ohms<br />Amperage = x<br />
  14. 14. Example of Ohm’s Law<br />Amps = 7<br />Resistance =2<br />Voltage = unknown (x)<br />
  15. 15. Electrical Symbols <br />Battery <br />
  16. 16. Basic Circuit <br />
  17. 17. Electrical Symbols <br />Fuse<br />
  18. 18. Basic Circuit <br />
  19. 19. Electrical Symbols <br />Switch<br />
  20. 20. Basic Circuit <br />
  21. 21. Electrical Symbols <br />Light Bulb<br />
  22. 22. Basic Circuit <br />
  23. 23. Electrical Symbols <br />Ground (Earth)<br />
  24. 24. Basic Circuit <br />
  25. 25. Basic Circuit <br />
  26. 26. Series Circuit <br />
