Turns ratio
The turns ratio in a transformer is the ratio of the number of turns in the primary, Tpri, to the number of turns in the secondary, Tsec. This ratio is written Tpri:Tsec or Tpri/Tsec.
In a transformer with excellent primary-to-secondary coupling, the following relationship always holds:
Epri/Esec = Tpri/Tsec
That is, the primary-to-secondary voltage ratio is always equal to the primary-to-secondary turns ratio (Fig. 1).
