dear all,

When loading the secondary winding of a transformer, my textbook gives the following relationships:
$$\frac{V_{sec}}{V_{pri}}=\frac{N_{sec}}{N_{pri}}\\$$
and
$$\frac{I_{sec}}{I_{pri}}=\frac{N_{sec}}{N_{pri}}\\$$

Do these relationships hold also when the diameter of the windings are different?
I suspect they don´t...If they do not, are there any other relationships I can use to calculate I and V in the secondary winding?

regards
t.
