In a 110-V compound generator, the
resistances of the armature, shunt
and the series windings are O.05 Q,
24 Q and 0.06 2 respectively. The
load consists of 150 lamps each rated
at 52 W, 110 V. Find the total
electromotive force, armature
current, mechanical power supplied
and efficiency when the machine is
connected (i) long shunt (ii) short
shunt. The drop voltage of each
* .brush is 1V, the stray loss is 400W
