Presentation Transcript

  1. Electricity is most commonly defined as the movement of electrons from a negatively charged location to a positively charged location

  2. ELECTRICAL TERMS E I / R VOLTS P I / E aka ELECTROMOTIVE FORCE (EMF), POTENTIAL CAN BE COMPARED TO THE PRESSURE IN A WATER LINE

  3. ELECTRICAL TERMS E I / R AMPERES P I / E aka AMPS, CURRENT CAN BE COMPARED TO THE FLOW RATE IN A WATER LINE

  4. ELECTRICAL TERMS E I / R WATTS P I / E aka POWER THE TOTAL AMOUNT OF ELECTRICITY USED OR AVAILABLE VOLTS X AMPS = WATTS

  5. ALTERNATING CURRENT MOST ELECTRICITY USED IS AC CURRENT FLOWS FIRST ONE WAY, THEN THE OTHER


  6. ALTERNATING CURRENT POSITIVE HALF CYCLE NEGATIVE HALF CYCLE

  7. ALTERNATING CURRENT 1\60 SECOND 1 HERTZ 1 CYCLE FREQUENCY

  8. ALTERNATING CURRENT PRODUCED BY: POWER PLANTS GENERATORS ALTERNATORS DYNAMOS

  9. AC POWER DISTRIBUTION

  10. AC POWER DISTRIBUTION SAFETY ! GROUNDING provides a path to earth for lightning

  11. ELECTRICAL POWER DISTRIBUTION SAFETY ! Bonding Wire BONDING provides an alternate path to neutral

  12. The Power Distribution System

  13. DIRECT CURRENT CURRENT FLOWS ALWAYS IN THE SAME DIRECTION

  14. DIRECT CURRENT PRODUCED BY: BATTERIES DISSIMILAR METALS RECTIFIED AC LIGHTNING LEMONS STATIC EELS

  15. RECTIFIED AC RECTIFIED AC: COMUTATOR DIODES RECTIFIED AC aka DC AC

  16. + AC/DC SUMMARY + +

  17. SERIES CIRCUITS

  18. PARALLEL CIRCUITS

  19. SERIES/PARALLEL CIRCUITS 3 VOLTS 2X AMPS

  20. SERIES – PARALLEL CIRCUITS SWITCH OPEN WHAT WILL HAPPEN TO THESE BIRDS WHEN THE SWITCH IS CLOSED??

  21. SERIES – PARALLEL CIRCUITS SWITCH CLOSED

  22. Voltage Drop & Resistance Since energy can not be created or destroyed, the electrical energy (voltage) that is “LOST” or “DROPPED” in a circuit is changed to: HEAT LIGHT MOTION Or sometimes a combination of all three.

  23. RESISTANCE & VOLTAGE DROP

  24. HIGH RESISTANCE = LOW CURRENT / HIGH VOLTAGE DROP

  34. Most wind turbines, large or small, generate three phase AC power. This is the same type of electricity produced in your car alternator or a municipal power plant.
