Multiple Choice

A three-phase generator has three single sets of ___________.

Explanation:
In a three-phase generator, there are three independent winding circuits that generate the three alternating voltages. Each phase needs its own winding so the magnetic field from the rotor induces a distinct, 120-degree shifted voltage in that winding. That’s why “windings” is the correct term: it refers to the complete set of conductors for each phase that, together, produce the three-phase output. Coils are smaller groups of turns that can form part of a winding, but a three-phase machine is described by its three windings as whole sets, not just individual coils. Laminations and cores are parts of the magnetic path in the machine; they support the flux but don’t define the number of electrical circuits (phases) being produced.
