The power factor of an induction motor under no-load conditions will be closer to_____________?
Correct answer: A. 0.2 lagging
- A. 0.2 lagging
- B. 0.2 leading
- C. 0.5 leading
- D. unity
Explanation
At no load, an induction motor still draws a substantial magnetizing current, which is highly reactive, while its useful-load current is small. Therefore its power factor is low and lagging, commonly near 0.2.
