    Modern cars use an alternator, older ones may have a generator.
  4. Whats the difference? An alternator is a small generator isn't it?
  5. Alternator, generator, dynamo, magneto... then there are also a pile of electrostatic machines too...

    If you were to buy one, the question is; what do you want it to do?

    High voltage, high current, low voltage, low current, AC, DC, pulsed..?
  6. An alternator produces AC a generator DC.
