DC Motors If a D.C. shunt motor is working at full load and if shunt field circuit suddenly opens Motor will come to stop Nothing will happen to motor This will make armature to take heavy current, possibly burning it This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses Motor will come to stop Nothing will happen to motor This will make armature to take heavy current, possibly burning it This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses 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 Motor will run at very slow speed Nothing will happen to the motor This will make armature to take heavy current, possibly burning it This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses Motor will run at very slow speed Nothing will happen to the motor This will make armature to take heavy current, possibly burning it ANSWER DOWNLOAD EXAMIANS APP
