Q 13 In any plant an engineer is designing a dc shunt motor in which an armature resistance of 0 060 and shunt resistance of 1150 have been connected When he gives supply of 230V dc then motor runs at a speed of 1500rpm Initially dc shunt motor works at no load and motor is taking 5A current Now when he adds any load then motor takes 21A current Then calculate a Back emf of dc shunt motor at no load b Back emf of dc shunt motor at full load c Ratio of speed at no load to full load
