As load on an induction motor goes on increasing______________?
Correct answer: D. its power factor goes on increasing up to full load and then it falls again
- A. its power factor goes on decreasing
- B. its power factor remains constant
- C. its power factor goes on increasing even after full load
- D. its power factor goes on increasing up to full load and then it falls again
Explanation
As load increases, the motor draws more active current and its power factor improves up to approximately full load. Beyond full load, increased slip and reactive effects cause the power factor to fall.
