In a step-up transformer, the voltage in the primary is $220 V$ and the current is $5 A .$ The secondary voltage is found to be $22000 V .$ The current in the secondary coil (neglect losses) is

Options:

Answer:

Solution:

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

$\Rightarrow I_{s} = I_{p} \times \frac{V_{p}}{V_{s}}$

$= 5 \times \frac{220}{22000} = 0 .05 A$
