4. A short shunt compound generator supplies a load of 10 kW at 200 V through a pair of feeder resistance of 0.10 ohm. Armature, shunt field resistance and series field resistance are 0.10 ohm, 52.5 ohms and 0.10 ohm, respectively. If the core, friction, and windage losses amount to 631 watts, determine (a) HP of driving engine (b) commercial, electrical and mechanical efficiencies.
