A shunt generator supplies 195 A @ 220 and the resistance of the shunt field and the armature are 44 & 0.02 , respectively. If the friction & iron losses amount to 1600 W, find a.) the generated emf (224 V) b.) total copper loss (1900W) c.) HP (62.1984) d.) electrical efficiency (95.7589%) e.) over-all efficiency (92.4568%)
