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.
