why dc supply given to ac alternator rotor

Answer Posted / hansraj

the dynamical induced emf needs a constant flux i.e time
invarient flux
if we give the ac input it produces alternating flux in the
rotar field and dc current not producec e.m.f. is induced
so the
electrical power will be zero

Is This Answer Correct ?    2 Yes 0 No
