DC Motors If a D.C. shunt motor is working at full load and if shunt field circuit suddenly opens This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses Motor will come to stop This will make armature to take heavy current, possibly burning it Nothing will happen to motor This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses Motor will come to stop This will make armature to take heavy current, possibly burning it Nothing will happen to motor ANSWER DOWNLOAD EXAMIANS APP
DC Motors If a D.C. shunt motor is working at no load and if shunt field circuit suddenly opens This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses This will make armature to take heavy current, possibly burning it Nothing will happen to the motor Motor will run at very slow speed This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses This will make armature to take heavy current, possibly burning it Nothing will happen to the motor Motor will run at very slow speed ANSWER DOWNLOAD EXAMIANS APP
