DC Motors If a D.C. shunt motor is working at no load and if shunt field circuit suddenly opens Motor will run at very slow speed This will make armature to take heavy current, possibly burning it Nothing will happen to the motor This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses Motor will run at very slow speed This will make armature to take heavy current, possibly burning it Nothing will happen to the motor This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses ANSWER DOWNLOAD EXAMIANS APP
DC Motors If a dc motor is comnected across the AC supply it will Burn due to heat produced in the field winding by eddy currents Not run Run at normal speed Run at lower speed Burn due to heat produced in the field winding by eddy currents Not run Run at normal speed Run at lower speed ANSWER DOWNLOAD EXAMIANS APP
