Example 29.2. A separately excited D.C. generator has armature circuit resistance of 0.1 ohm
and the total brush-drop is 2 1. When running at 1000 r.p.m., it delivers a current of 100 A at 250 T
to a load of constant resistance. If the generator speed drop to 700 r.p.m., with field-current
ered, find the current delivered to load.
