For a consumer the most economical power factor is generally____________?
Correct answer: C. 0.95 lagging
- A. 0.5 lagging
- B. 0.5 leading
- C. 0.95 lagging
- D. 0.95 leading
Explanation
A consumer generally operates most economically at a high power factor, commonly taken as about 0.95 lagging. A lagging value reflects the inductive loads normally found in consumer installations, while a leading factor is not usually required.
