D.C. generators are normally designed for maximum efficiency around_____________?
Correct answer: A. full-load
- A. full-load
- B. rated r.p.m.
- C. rated voltage
- D. all of the above
Explanation
A DC generator is normally designed so that its highest efficiency occurs close to full-load operation, where its fixed losses and load-dependent losses are suitably balanced. Rated speed and voltage are operating ratings, not the direct efficiency condition.
