A shunt-wound 12-pole 500Kw dynamo, with simplex-lap wound armature has a terminal emf of 600V @ full- load. The armature is wound with 5,000 ft of copper wire of 40,000 cir mils cross section. Assuming 2 volts drop at the brushes, and neglecting the current in the field coils, calculate the emf which must be developed in the armature at full-load. (ohms per circular mil-foot = 12)
