🔍 Key Concepts

• Transformer VA rating and what it represents • Relationship between VA, volts, and amperes in a single‑phase circuit • Which side of the transformer (primary or secondary) the 120 VAC applies to in the question

💭 Think About

• From the information given, ask: is the 600 VA rating tied to power, current, or voltage? • Decide which voltage (480 V or 120 V) you should use to find the secondary current. • Use the basic formula that links VA, voltage, and current, then solve for current and compare your result to the answer choices.

✅ Before You Answer

• Be sure you are using the secondary voltage (120 VAC) when finding the secondary current. • Confirm you are using the correct formula: VA = Volts × Amps for single‑phase. • After calculating, check that your current value is close to one of the listed choices and not off by a factor of 10 or 100.
