A transformer is having $2100$ turns in primary and $4200$ turns in secondary. An AC source of $120 V$ , $10 A$ is connected to its primary. The secondary voltage and current are

Options:

Answer:

Solution:

$E_{s} = \frac{n_{s}}{n_{P}} E_{P} = \frac{4200}{2100} \times 120 = 240 V$

$i_{s} = \frac{n_{s}}{n_{P}} i_{P} = \frac{2100}{4200} \times 10 = 5 A$
