DC Motors If a D.C. shunt motor is working at full load and if shunt field circuit suddenly opens 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 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 ANSWER DOWNLOAD EXAMIANS APP
DC Motors In D.C. shunt motors as load is reduced The speed will increase abruptly The speed will increase in proportion to reduction in load The speed will remain almost/constant The speed will reduce The speed will increase abruptly The speed will increase in proportion to reduction in load The speed will remain almost/constant The speed will reduce ANSWER DOWNLOAD EXAMIANS APP
