Identify the given values for the transformer.
Primary voltage, $V_p = 200 \text{ V}$
Primary current, $I_p = 30 \text{ A}$
Output voltage, $V_s = 450 \text{ V}$
Output current, $I_s = ?$
Apply the principle of conservation of power for an ideal transformer.
For an ideal transformer, the input power equals the output power.
$P_p = P_s$ $V_p I_p = V_s I_s$
Substitute the known values into the equation and solve for the output current $I_s$ .
$(200 \text{ V}) \times (30 \text{ A}) = (450 \text{ V}) \times I_s$ $6000 \text{ VA} = 450 \text{ V} \times I_s$ $I_s = \frac{6000 \text{ VA}}{450 \text{ V}}$ $I_s = \frac{600}{45} \text{ A}$ $I_s = \frac{40}{3} \text{ A}$ $I_s \approx 13.33 \text{ A}$
The output current is approximately $13.33 \text{ A}$ . This matches option C.
