when 1 phase ac supply is given to the field of an alternator, it produces statically induced emf and dynamically produced emf as a result, the net torque will be zero and it produces hunting in the rotor. hence there is no output as the net torque is zero.

it is in our knowledge tht right plug of supply of residential suppy system is phase n other is neutral...howevr the battery charger of mobile works in both ways...i mean it is not restricted in only one direction.ny of the holder of charger can hav phase .so y is it not lik tht phase of supply must b connected 2 phase of charger...?
