what happens when ac supply is given to D.C motor.
Answer Posted / manish
dc motor does no work on ac.it will not rotate because in
india ac frequency is 50 hz so the time of half cycle is
only 10 ms.this time is too short to move because of its
inertia.
but expeptionaly dc series motor will rotate when it is
given to ac supply.
