In a step-up transformer, the ratio of turns of primary to secondary is $1 : 10$ and the primary voltage is $230 V$ . If the load current is $2 A$ , then the current in the primary is

Options:

Answer:

Solution:

$\frac{N_{p}}{N_{s}} = \frac{1}{10}$

$V_{p} = 230 V, I_{s} = 2 A,$

$\frac{I_{p}}{I_{s}} = \frac{N_{s}}{N_{p}}$

$\frac{I_{p}}{2} = \frac{10}{1}$

$⇒$ $I_{p} = 20 A $
