🔍 Key Concepts

• Step-up vs. step-down transformers and how they change voltage • The relationship between number of turns in the coils and voltage • Basic transformer formula: voltage is proportional to the turns ratio

💭 Think About

• If a transformer increases voltage from primary to secondary, how must the turns on the secondary compare to the primary? • What happens to the voltage when the secondary has fewer turns than the primary? More turns? • Which option matches the turns relationship needed to increase (step up) the output voltage?

✅ Before You Answer

• Recall that V_primary / V_secondary = N_primary / N_secondary (V = voltage, N = number of turns) • Identify which side (primary or secondary) has the higher voltage in a step-up transformer • Match the correct turns ratio (more or fewer turns on secondary) that gives a higher secondary voltage
