🔍 Key Concepts

• Transformer basics – relationship between primary and secondary coils (turns ratio) • How voltage and current change in an ideal transformer when it is a step-down type • Approximate power balance (P = V × I) between primary and secondary in an ideal transformer

💭 Think About

• If the transformer is called step-down, which quantity (voltage or current) must be reduced from primary to secondary? • In an ideal transformer, if voltage goes down but power stays about the same, what must happen to current? • Look at each choice and ask: does it match both the meaning of step-down and conservation of power?

✅ Before You Answer

• Identify which side (primary or secondary) has lower voltage in a step-down transformer • Check how current must change if voltage decreases but power (V × I) is approximately constant • Eliminate any option where both voltage and current change in the same direction (both up or both down) and think about whether that fits power balance
