When a transformer is used to step down voltage, what statement is true?

🔍 Key Concepts

• Step-up vs. step-down transformer and how voltage and current change between primary and secondary windings • Relationship between primary winding (input side) and secondary winding (output side) • Basic construction of a transformer: core, insulated windings, and how they are arranged

💭 Think About

• Which side of a step-down transformer is connected to the higher voltage source: primary or secondary? • If voltage is reduced from primary to secondary, what happens to current on the secondary side in an ideal transformer? • Would any winding in a transformer ever be left uninsulated or built as part of the magnetic core itself?

✅ Before You Answer

• Identify which winding is on the input (supply) side and which is on the output (load) side in a step-down transformer • Confirm that all windings are insulated from the core for safety and function • Remember that the core is iron/steel for magnetism, not copper wire for carrying current
