An ideal __________ is one in which all the lines of force produced by the primary winding inductively link every turn of the secondary winding.

An ideal __________ is one in which all the lines of force produced by the primary winding inductively link every turn of the secondary winding.

• A. Transformer
• B. Capacitor
• C. Inductor
• D. Reactor

Answer: (A)

This describes ideal magnetic coupling in a transformer: all the lines of force produced by the primary link every turn of the secondary. In that perfect linking, there’s no leakage flux and no core losses, so energy transfer is governed solely by the turns ratio between primary and secondary. That exact behavior is the defining feature of an ideal transformer. Capacitors don’t involve magnetic flux linking windings, and an inductor or reactor typically has a single winding without a secondary to transfer energy to; they don’t exhibit this complete flux linking between windings.
