Reference: OCR
The number of turns in the primary coil divided by the number of turns in the secondary coil, equal to the ratio of the two coil voltages.
The ratio of the potential differences across the two coils equals the ratio of the numbers of turns in each, so Vp/Vs = Np/Ns.
The ratio of secondary to primary turns equals the ratio of secondary to primary potential difference.
