A 4-pole lap wound DC shunt generator has an open e.m..f of 250V when the flux per pole is 0.08 Wb and the speed is 10 rev/sec. The speed of the generator is reduced to 10 per cent and the flux per pole is increased by 5% when the generator supplies a load of 100A. Determine the terminal voltage, if the armature resistance is 0.06 ohm and the new total field circuit reisitance is 200 ohm. (16)
