The relationship for the current ration $($Isec$/$lpri$)$ in a transformer is:

less than the turns ratio $(Ns\frac{ec}{\text{N}\text{p}\text{r}\text{i}}).$

the same as the turns ratio $(Ns\frac{ec}{\text{N}\text{p}\text{r}\text{i}}).$

more than the turns ratio $(Ns\frac{ec}{\text{N}\text{p}\text{r}\text{i}}).$

the inverse of the turns ratio $(Ns\frac{ec}{\text{N}\text{p}\text{r}\text{i}}).$
