B4. A 4 pole DC shunt generator with lap wound armature having 389 conductors, has to supply a load of 506 lamps each of 100 W at 250 V. Allowing 10 V for the voltage drop in the connecting leads between the generator and the load with each brush drop of 2 V. The flux per pole is 31 mWb, Ra = 0.29 ohms and Rsh = 73 ohms. Calculate the armature current and the speed at which the generator should be driven. [ The armature current is The speed of machine is
