Each complete revolution (360° travel) of the loop of wire in an AC generator is called a(n) ?

In the context of an AC generator, each complete revolution of the loop of wire corresponds to what is known as a cycle. This cycle represents a full movement through the waveform generated by the alternating current, indicating that the electrical output has returned to its original position.

A cycle is an important concept in alternating current electrodynamics because it reflects the periodic nature of AC voltage and current, which reverses direction periodically. This is directly tied to the revolving motion of the generator’s armature, completing one full sine wave or one complete electrical oscillation.

While terms like period and rotation may seem relevant, they refer to different aspects of motion or time. The period relates to the time it takes to complete one cycle, while rotation focuses more on the physical spinning aspect of the generator. Therefore, referring to each complete revolution as a cycle is the most accurate terminology within the context of AC generators.
