The efficiency of an induction motor can be expected to be nearly____________?
Correct answer: B. 80 to 90%
- A. 60 to 90%
- B. 80 to 90%
- C. 95 to 98%
- D. 99%
Explanation
A practical induction motor commonly achieves about 80% to 90% efficiency, depending on its rating and load. The 95% to 98% range is possible for some large, premium motors but is not the usual general value.
