A 50-kW, 230-V compound generator has the following data: armature-circuit resistance 0.05 Ω, series-field circuit resistance 0.05 Ω, and shunt- field circuit resistance 125Ω. Assuming the total brush-contact drop to be 2 V, find the induced armature voltage at rated load and rated terminal voltage for:
(a) short shunt, and
(b) long-shunt compound connection.
