The correct formula for computing the amount of voltage applied to the load, especially in the context of transformers, is $EP / ES = NP / NS$. This formula represents the relationship between primary and secondary voltages ($EP$ and $ES$, respectively) and the number of turns in the primary and secondary coils ($NP$ and $NS$, respectively), indicating that the voltage ratio is equal to the turns ratio.
