Power transformers are designed to have maximum efficiency at___________?
Correct answer: A. nearly full load
- A. nearly full load
- B. 70% full load
- C. 50% full load
- D. no load
Explanation
Power transformers generally operate near their rated load, so they are designed to have maximum efficiency near full load. This differs from distribution transformers, which often peak near 50% load because they remain energized for long periods.
