Answer / pandi

in A.C generator D.c supply is given to field winding for
excitation. field also rotated by prime mover.according to
faradaya law (whenever current carrying conductor cuts the
magnetic flux lines dynamically emf produced the coil) EMF
induced in stator winding

Answer / v.arunkumar

d.c generator works on the principle of faradays law of e.m
induction.when ever the flux cut the conductor emf is
induced

Answer / kapil bahadure

ac generator: its work on the principles of electro
magnetic induction.according to the faradays law.
dc generator:-whenever current carring conductor placed in
magnetic field then rotating magnetic field produced in it.
