As an engineer I look up for formulas and experiments that I can find arround in order to come up with my own ideas and design.

As we know, this is the formula to calculate the amount of turns for primary winding for a given core and frequency:

N(p) = (Vin x 10^8) / (4 B A f).

For the secondary winding I understand that its a rule of 3 calculation based on finding of the primary set of winding.

Question:

Based on the above formula, does that mean at that given value of Freq and findings of the primary and secondary set of winding for this transformer core, it will operate at resonance

__regardless__of the input voltage ?
