Question

the armature series field and shunt field resistance of a 125 kw, 250V long shunt cumulative compound DC generator are 0.025ohms, 0.01ohms and 30 ohms, respectively. If the stray power stray loss at rated load is 25 kW, determine the power in the shunt field. Assume a astray load loss of 1% of the load power output (note: Input power generator is equal to the motor brake horsepower, Pin=Pl+Plosses)
