At 100 kw A shunt generator rated and 460 v was run as A motor on no load at its rated voltage and speed, the total current taken from the supply is 9.8 A, including a shunt field current of 2.7 A. The resistance, at normal working temperature, of the armature circuit was 0.11 ohm. Find the efficiency of the generator both at: |(a) half load. | (b) Full load.
