🔍 Key Concepts

• Transformer turns ratio and how it relates primary voltage to secondary voltage • How to set up the ratio using primary voltage : secondary voltage for a step-down transformer • Converting a large voltage (4160 VAC) down to a small control voltage (120 VAC)

💭 Think About

• First write the voltage ratio as 4160 V : 120 V and simplify that fraction—what number do both values divide by? • Once you have the simplified voltage ratio, match it to a turns ratio in the form N(primary) : N(secondary). • Be careful about which side (primary or secondary) has more turns in a step-down transformer—does the higher voltage side have more or fewer turns?

✅ Before You Answer

• Verify that the primary side of this transformer is at 4160 VAC and the secondary is at 120 VAC feeding the AVR. • Check that you simplified 4160/120 completely to the smallest whole-number ratio. • Confirm that your final ratio is written in the same order as the choices (turns on primary : turns on secondary or vice versa) so you don’t pick a flipped answer.
