- No, there's no repeal of the laws of physics in an alternator
- either. Current output goes up with rpm...after all work out
- is related to work in.

- The output current increases until the voltage regulator kicks in
- and then stays pretty constant. Some have multi-stage regulators
- to help produce high current at low rpm....as driving at night
- with the A/C, radio, and lights on can easily discharge a battery
- if this isn't done. (And if that low-rpm stage fails, as it did
- on one of my cars, your battery DOES go flat in town...)
