Q

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?

🔍 Key Concepts

• Single-phase power formula: Relationship between real power (kW), voltage (V), current (A), and power factor (pf) • Difference between apparent power (kVA) and real power (kW) • How to correctly convert between primary and secondary side quantities in a transformer problem

💭 Think About

• How do you calculate the apparent power (kVA) when you know real power (kW) and power factor? • Once you know apparent power, how can you relate it to voltage and current on the secondary side? • Are you supposed to use the 440 V or 110 V value when finding the secondary current in this question?

✅ Before You Answer

• Be sure you are using the secondary voltage in your current calculation, not the primary voltage • Confirm you are using the correct formula: P = V × I × power factor (and how that relates to kVA) • After finding the current, check if your result is in the same range as any of the multiple-choice options before rounding.
