5-A four pole lap-connected armature of a DC shunt generator is required to supply the loads connected in parallel: (a) 5kW Geyser at 250 V and (b) 2.5kW lighting load also at 250V. The generator has an armature resistance 0.22 and a field resistance of 2502. The armature has 120 conductors in the slots and runs at 1000 rpm. Allowing 1V per brush for contact drops, find (1) Flux per pole, (2) armature current per parallel path

Question
5-A four pole lap-connected armature of a DC shunt generator is
required to supply the loads connected in parallel: (a) 5kW Geyser at
250 V and (b) 2.5kW lighting load also at 250V. The generator has an
armature resistance 0.22 and a field resistance of 2502. The
armature has 120 conductors in the slots and runs at 1000 rpm.
Allowing 1V per brush for contact drops, find (1) Flux per pole, (2)
armature current per parallel path
