what is the difference between ac and dc generator
Answer Posted / nandhini
in dc generator,rotor consists of armature conductor and stator consists of field windings.in ac generator,rotor consists of field magnet and stator consists of armature conductor. in dc generator commutator is used to convert it to dc but in ac generator no commutator is used. ac generators are also called as alternators. in dc generators split rings are used for phase displacement .in ac generators slip rings are used.
