Exercise 2 A shunt generator delivers 14A at 270V and the resistance of the shunt field and armature are 100 Q and 0.75 Q2, respectively. Calculate: i. The generated emf and the efficiency of this operating condition. ii. The generated emf if the shunt field impedance was triple and if it was double and the efficiency of these cases. iii. What emf could serve tha same active power of load but at load voltage of 240V and the efficiency in this case.
