The value of exciting or magnetizing current depends upon which of the following factors ?
Correct answer: D. All of the above
- A. Total m.m.f. required
- B. The number of turns in the exciting winding
- C. The way in which the winding is distributed
- D. All of the above
Explanation
Magnetizing current follows approximately from I = MMF/N, so it depends on the required total MMF and the number and distribution of winding turns that produce it.
