Q1// Answer the following question. 1- A 8-pole a separately excited generator, having the wave-wound armature winding has 16 slots, when running at 600 r.p.m. has a terminal voltage of 400 V and an induced voltage of 414.72 V. The armature resistance is 0.1N, the flux per pole is 36 mWb, and there is a brush contact voltage drop of 1V at each brush. Calculate the value of armature current and the number of conductors for each slot. 2- A six-pole, DC shunt generator is wave-connected, supplies a load of A 12 kW, 240 V and an induced voltage of 250 V. If this machine is now lap-connected and flux per pole increasing by 20%, all other things remaining the same, calculate the e.m.f generated and load current.
