1. The armature of a 4-pole, 136 slots shunt generator is lap wound with four conductors per slot. The flux per pole is 80 mWb. The armature and shunt field resistances are 0.04 Q and 50 Q respectively. Determine the speed of the machine when supplying 400 A at a terminal voltage of 250 V. 2.A DC series generator is supplying a current of 10 A to a series lighting system through a feeder of total resistance of 2 Q. The terminal voltage is 2500 V. The armature and series field resistances are respectively 20 and 10 0, respectively. A 15-Q diverter resistance is shunted across the series field. Determine the power developed in the armature of the generator.
