FREQUENCY EFFECT ON TRANSFORMER OUTPUT (50/60 Hz)

A Transformer  Which one will give more Output? (operates on 50 or 60 Hz frequency?)

Which is mostly asked in an interview for Electrical Power Engineering Jobs.

For Example:

we will solve this using suppose values :

Let

When Transformer operates on 50 Hz Frequency Transformer =100kVA, R=7000, L=1.2 H, f= 60 Hz

We know = XL = √(2πfL)
