Which of the following would be used to calculate transformer turns ratio?
- Secondary turns / primary turns.
- Primary turns * secondary turns.
- Primary turns / secondary turns.
Explanation
The transformation ratio used to find the output is secondary turns divided by primary turns, since Vs = Vp x (Ns/Np). Multiplying the turns together has no physical meaning, and primary divided by secondary would give the inverse ratio, predicting the opposite of the actual voltage change.

isn't this wrong?

Hello.
But I have other information: http://www.pdf-archive.com/2013/06/04/transformer/
Actually if we are talking about the American version of turns ratio is used it is Primary:Secondary. English notation is Secondary:Primary.

Hi JD2016.
It was encoding issue, I have corrected that.
