For a DC generator, given the load current is 510 ampere, field current is 1.4 ampere. What is the value of armature current?

(a) 508.6 ampere

(b) 714 ampere

(c) 511.4 ampere

(d) 364.28 ampere

I have been asked this question in unit test.

The origin of the question is Design of Armature in portion Thermal Design Aspects of Electrical Machines & D.C of Design of Electrical Machines

Correct answer is (c) 511.4 ampere

Best explanation: For DC generator, Armature Current = Load Current + Field Current

Armature Current = 510 + 1.4 = 511.4 ampere.
