directly proportional to power used. perhaps you are correct in that the altanator is designed for a specific power output, and that output will not change by rpm, but the regulator will drop in and out the field based on demand.
Hmm, perhaps you are confusing power with amperage... the same 14.4 volts will be produced no matter how much you turn the rpm's due to the VOLTAGE regulator bringing in and out the circuit.
imho

Yes and no. In a generator, natural magnets are used hence the same power is always generated, the regulator dissapates the energy. On an alternator that magnetic field is regulated by the regulator. So in reality an alternator is much more efficient than the generators of old.
