Three shunt generators operating in parallel supply a total load current of 2000 amperes. Each machine has a field resistance of 40 ohms and an armature resistance of 0.025 ohm. The emfs generated are 240, 245, 250 volts respectively. Determine the current delivered by each generator.

There are 160 slots in a 3-phase, 8-pole, 50 Hz., star connected alternator. There are 4 conductors in each slot and all the conductors in a phase are connected in series. Coil span is 150° electrical and the flux per pole is 0.08 Weber sinusoidally distributed. Calculate the emf induced per phase.

An Armature runs at 250 r.p.m. and generates an e.m.f. at 50 Hz. There are 216 slots each containing 5 conductors. The winding is distributed and full pitch. All the conductors of each phase are in series and flux per pole is 30 mWb which is sinusoidal distributed.Calculate the number of pole.
