🔍 Key Concepts

• Step-down potential transformer basic function (primary vs secondary voltage) • Relationship between voltage and current in an ideal transformer • Approximate conservation of power (VA) between primary and secondary in a transformer

💭 Think About

• If the transformer reduces voltage on the secondary side, what must generally happen to current if power (VA) stays about the same? • Look at each choice: which one correctly describes what happens to both voltage and current in a step-down transformer? • Does a typical step-down potential transformer primarily change voltage, current, or total power rating?

✅ Before You Answer

• Verify which option shows lower secondary voltage than primary for a step-down transformer • Check which option shows the correct current behavior when voltage is reduced but power is approximately conserved • Confirm that a transformer mainly transforms voltage and current, not the kVA rating of the load itself
