No-load current of a transformer has_____________?
Correct answer: D. has small magnitude and low power factor
- A. has high magnitude and low power factor
- B. has high magnitude and high power factor
- C. has small magnitude and high power factor
- D. has small magnitude and low power factor
Explanation
At no load, a transformer draws only a small exciting current, most of which is magnetizing current and therefore reactive. Consequently, the no-load current has a low power factor.
