This small voltage sends a small current throughthe field coils, which increases the magnetic flux and causes thegenerated voltage to increase, and this in turn… … Exciting Current If Fig. 96—Magnetization curve of a shunt generator. circuit becomes more nearly saturated and the voltage increasesby a smaller and smaller amount until finally, when the point A isreached at which E0/If = Rf, the voltage and exciting currentcan increase no further.
