In an alternator, the armature winding is kept stationary while the field winding is kept rotating for the following reasons:1. Armature handles very large current and high voltage2. Armature fabrication, involving deep slots to accommodate large coils, is easy if armature is kept stationary3. It is easier to cool the stator than the rotorWhich of the above reasons are correct?
