A 5kW shunt generator having an Armature circuit Resistance of 0.20 and a field resistance of 500, generates a terminal voltage of 220 V at full load. Find the Efficiency of the Generator at full load. Assume the Iron, Friction, and Windage losses are 0.2 kW.

A 8-pole dC generator running at 1,200 rpm, and with a flux of 25 m Wb per pole generates 440 V. Calculate the number of conductors, if the armature is : (i) lap-wound, (ii) wave- wound.

A 6 pole wave wound d.c. shunt generator has 500 conductors. A generator delivers 50 kW of power at 250 voltage at full load. The resistance of the field circuit is 125 2. Actual brush shift is 10°. Then find the demagnetizing and cross magnetizing ampere turns per pole and how many additional turns must be wound on each pole to eliminate the demagnetizing effect.
