6. A 4 pole DC shunt generator with wave wound armature having 390 conductors has to supply a load of 500 lamps each of 100W at 250 V. Allowing 10 V for the voltage drop in the connecting leads between the generator and the load and brush drop of 2V. Calculate the speed at which the generator should be driven. The flux per pole is 30mWb and Ra = 0.05 ohms and Rsh = 65 ohms.
