Question

The no load current of the transformer is very less due to _________

(a) mutual flux having low reluctance iron core

(b) mutual flux having high reluctance iron core

(c) leakage flux having low reluctance iron core

(d) leakage flux having high reluctance iron core

I had been asked this question by my school principal while I was bunking the class.

I'm obligated to ask this question of Induction Motor as a Transformer topic in portion Induction Machines of Electrical Machines

Answer 1

Correct answer is (a) mutual flux having low reluctance iron core

The best explanation: It is due to the low reluctance path, the flux requirement is low in the transformer.
