Two single phase transformers A and B are operating in parallel having different impedance and identical x/r ratio. Then?

(a) A has poorer pf than B

(b) B has poorer pf than B

(c) lesser power factor angle

(d) both operate at same power factor

I got this question in a national level competition.

My query is from Parallel Operation of Single Phase Transformers topic in chapter Transformers of Electrical Machines

Best answer
Correct option is (d) both operate at same power factor

Easiest explanation: As the x/r is same, this supports that they should have same leakage impedance angles.
