🔍 Key Concepts

• Transformer turns ratio relationship between primary and secondary voltages and turns • Direct proportion between voltage and number of turns in ideal transformers • How to set up a simple ratio using given primary voltage, primary turns, and secondary turns

💭 Think About

• How does the voltage change when the number of turns decreases from primary to secondary? Is this a step-up or step-down transformer? • Write the proportion using Vp/Np and Vs/Ns. What must stay equal on both sides of the equation? • After you solve for the secondary voltage using the ratio, which of the choices is closest to your calculated value?

✅ Before You Answer

• Confirm you are using the formula Vp / Np = Vs / Ns correctly • Check that you substituted primary and secondary values in the right places (don’t swap them) • After calculating Vs, compare the size of Vs to Vp and ask: does this direction of change (higher or lower) make sense with fewer secondary turns?
