What is the relation between the magnetizing current and power factor?(a) magnetizing current is directly proportional to the power factor(b) magnetizing current is indirectly proportional to the power factor(c) magnetizing current is directly proportional to the square of the power factor(d) magnetizing current is indirectly proportional to the square of the power factorI had been asked this question by my school principal while I was bunking the class.This interesting question is from Dispersion Coefficient topic in section Three Phase Induction Motor of Design of Electrical Machines

Answer»

Correct answer is (a) magnetizing current is DIRECTLY proportional to the power FACTOR

Easiest explanation: Magnetizing current is indirectly proportional to the power factor. As the magnetizing current is LARGE, the power factor is poor.
