A power transformer has $50$ turns for primary and $300$ turns for secondary. What is turns ratio? How much is secondary voltage with primary voltage of $230$ $V$ ?

Open in App

Solution

$N_{1} = 50$ and $N_{2} = 300$
Turn ratio $= \frac{300}{50} = 6$
$\frac{E_{1}}{E_{2}} = \frac{V_{1}}{V_{2}} = \frac{N_{1}}{N_{2}}$
$∴ V_{2} = \frac{N_{2}}{N_{1}} \times V_{1} = 6 \times 230 = 1380$ $V$
