An over-excited synchronous motor takes__________?
Correct answer: A. leading current
- A. leading current
- B. lagging current
- C. both A. and (b)
- D. none of the above
Explanation
Increasing field excitation beyond the unity-power-factor point makes a synchronous motor over-excited, causing it to draw leading current. This leading current can compensate lagging current in other loads.
