Question

In a transformer ______ decreases with increase of the leakage flux.

(a) secondary terminal voltage

(b) secondary induced voltage

(c) primary induced voltage

(d) all of the mentioned

I have been asked this question by my college professor while I was bunking the class.

This interesting question is from Equivalent Circuit of Transformer in section Transformers of Electrical Machines

Answer 1

Correct answer is (a) secondary terminal voltage

Easiest explanation: The leakage is modelled as the reactance which incurrs as a loss to the terminal voltage not the induced voltage.
