Q2/ a) A separately excited DC generator when running at 1200 rpm supplies 200 A at 125 V to a circuit of constant resistance. What will be the load current when the speed is dropped to 1000 rpm: i) if the field current is unchanged. ii) if the field current is reduced to 80%? Armature resistance, 0.040 and total drop at brushes, 2V. Ignore saturation and armature reaction.
