(b) false

I had been asked this question in an interview for job.

Question is taken from Dispersion Coefficient topic in chapter Three Phase Induction Motor of Design of Electrical Machines

Answer 1

The correct answer is (a) true

For explanation I would say: The increase in number of poles increases the dispersion coefficient. The increases in dispersion coefficient gives a low power factor.
