A 6 pole DC shunt generator with wave wound
armature having 384 conductors has to supply a
load of 514 lamps each of 100 W at 250V.
Allowing 12 V for the voltage drop in the
connecting leads between the generator and the
load and total brush drop of 2 V. Calculate the
armature current and the speed at which the
generator should be driven. The flux per pole is 31
mWb and Ra = 0.13 ohms and Rsh = 75 ohms.
