3 A shunt generator supplies a 50 kW load at 400 V through cables of resistance 0.2 2. If the field winding resistance is 50 2 and the arma- ture resistance is 0.05 2, determine (a) the ter- minal voltage, (b) the e.m.f. generated in the [(a) 425 volts (b) 431.68 volts] armature 4 A short-shunt compound generator supplies 50 A at 300 V. If the field resistance is 30 2, the series resistance 0.03 2 and the armature resistance 0.05 $2, determine the e.m.f. gener- ated [304.5 volts]
