Step 1

1 of 4Relationship between primary and secondary voltages is given by the relation

$\begin{align*} \frac{ \text{primary voltage} }{ \text{number of primary turns} } &= \frac{ \text{secondary voltage} }{ \text{number of secondary turns} }. \tag{1} \end{align*}$

We can rearrange relation (1) to get

$\begin{align*} \frac{ \text{number of secondary turns} }{ \text{number of primary turns} } &= \frac{ \text{secondary voltage} }{ \text{primary voltage} }. \tag{2} \end{align*}$
