How is mechanical energy converted to electrical

  1. May 7, 2006 #1
    in, for example a hand cranked generator, or even a hydrocarbon based generator, when there is no ionisation/ oxidation-reduction going on to produce the electrons... where are they coming from? i know how such a generator is physically put togther, but where are the electrons coming?

    The electrons that make up the current are in the wires all along. The generator doesn't "create" any new ones. It simply pushes them along.

    could you explain this more in depth(as in the jumping of the electrons from atoms orbitals)
