What is the nature of the voltages produced by a 3-phase generator?

The voltages produced by a 3-phase generator are equal in magnitude and phase relationship to each other, which is a foundational characteristic of three-phase power systems. Each phase in a three-phase generator generates an alternating current (AC) voltage that reaches its peak at 120-degree intervals, resulting in a balanced system where the sum of the voltages at any moment is zero.

This equality in voltage levels contributes to efficient power delivery and reduces the likelihood of voltage fluctuations, enabling more stable operation of motors and other equipment connected to the three-phase system. The balanced nature of the phases also helps in minimizing losses and maximizing the overall performance of an electrical system.

While the other options suggest potential variations in voltage, they do not accurately represent the key characteristic of a three-phase generator, which is the consistency and equality of the voltages generated across the phases.
