A 440/110 V single phase transformer supplies a load of 5 kW at 0.8 power factor load. What will be its secondary current ignoring transformer power losses?

Correct Answer: Option B — 56.82 A

Ignoring losses, the apparent power of 6,250 VA (5 kW divided by 0.8 power factor) remains constant across the transformer. Dividing this apparent power by the secondary voltage of 110 volts yields a secondary current of 56.82 amps, demonstrating the inverse relationship between voltage and current.
