🔍 Key Concepts

• transformer basic function in AC (alternating current) circuits • how a changing magnetic field can create voltage in another coil (induction) • difference between effects that happen in a single coil vs. between two coils

💭 Think About

• Which choice describes an effect that specifically involves two separate windings or coils interacting with each other? • Does a transformer work by changing current directly, or by using a magnetic field linking a primary and a secondary winding? • Which term is commonly used in basic electricity/electronics when one circuit induces a voltage in another nearby circuit without physical contact?

✅ Before You Answer

• Identify which options refer to a process involving two coils influencing each other via a magnetic field. • Eliminate any options that describe mechanical forces rather than electrical/magnetic coupling. • Recall from basic electrical theory: transformers operate on AC and a changing magnetic field, not on increasing power itself.
