Answer Posted / b.dayakar reddy
>>When A.C. supply is given to a D.C. motor,
1)In case of Series connection of armature winding and field winding , it may run.
2)But, In case of parallel connection , it won't rotate at all and will start humming and will create vibrations, as a torque produced by positive and negative cycle will cancel out each other. D.C. motor will be heated up.
