How many degrees of rotation does a two-pole alternator complete in one full cycle of alternating current?

A two-pole alternator completes a full cycle of alternating current in 360 degrees of rotation. This is because the alternator operates on the principle of electromagnetic induction, where each complete rotation of the rotor corresponds to one full cycle of the AC waveform produced.

In a two-pole configuration, there are two magnetic poles (one north and one south) on the rotor, and as the rotor rotates 360 degrees, the magnetic field moves past the stator coils, inducing an alternating current. This rotation creates one complete sine wave of alternating voltage, which is represented graphically as one cycle of 360 degrees.

Understanding this concept is crucial because the relationship between mechanical rotation and electrical output is a fundamental principle of how generators work. The other options do not apply here because they either exceed or do not complete the full cycle of electrical generation in the context of a two-pole alternator.
