Why voltage regulation of an alternator is negative for a leading power factor?

Answer / arijeet chakraborty
In case of leading load that means capacitive load, the effect of armature flux on main field flux is magnetising i.e, the armature flux is adding up with the main field flux. Since it is adding up, the total induced emf(V) will also be more than the induced emf at no load(E).
Therefore voltage regulation= -ve

Answer / md al mamun
in case of leading power,terminal voltage will fall on removing the full load,in this case voltage regulation is negative.
