DC Motors The armature torque of the D.C. shunt motor is proportional to armature current only None of these field flux only both (A) and (B) armature current only None of these field flux only both (A) and (B) ANSWER DOWNLOAD EXAMIANS APP
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 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 Nothing will happen to motor Motor will come to stop 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 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
