It's not bad Tom.... An alternator is a rotating transformer, with similar i/o characteristics to a static transformer. So there is a reasonably linear relationship between Power-in and Power-out, where Power-in is Torque*Speed for the rotating transformer, against V*I(inphase) for the static transformer. -- Tony Williams.
