n an industry an engineer is designing a dc shunt machine which behaves as a motor. He is connected an armature resistance of 0.080 and shunt resistance of 2400 in dc shunt motor. When he gives supply of 240V dc then motor runs at a speed of 1000rpm. Initially dc shunt motor works at no-load and motor is taking 5A current. Now when he places a load so motor takes 41A current. Then evaluate: (a) Armature current in dc shunt motor. (b) Back emf in dc shunt motor.
