A simple power transformer essentially consists of two ______.

• A. Windings
• B. Coils
• C. Inductors
• D. Rectifiers

Answer: (A)

Two windings wound on a common magnetic core form the basic structure of a simple power transformer. The primary winding receives alternating current, which produces a changing magnetic flux in the core. This flux links to the secondary winding and induces a voltage in it, with the voltage ratio set by the turns ratio between the windings. The energy transfer happens through magnetic coupling between these two windings, so there’s no direct electrical connection between input and output. While windings (or coils) describe the conducting turns, the defining feature here is having two windings on a shared core. Inductors typically have a single winding and store energy in the magnetic field, not transfer it to a separate circuit, and rectifiers convert AC to DC and are not the transformer itself.
