In electrical terms, how is a 720-degree electrical rotation defined?

• A. One complete mechanical revolution
• B. Two complete mechanical revolutions
• C. One and a half mechanical revolutions
• D. Three electrical phases

Answer: (B)

A 720-degree electrical rotation is defined as two complete mechanical revolutions. This is because a full mechanical revolution corresponds to a 360-degree rotation. Therefore, to achieve a rotation of 720 degrees, one must perform not one, but two full rotations (360 degrees each). In electrical systems, understanding the relationship between electrical rotation and mechanical revolutions is essential, especially in the context of motors and generators where these concepts are interconnected. Each phase in a three-phase system, for example, contributes to the overall electrical output and efficiency, and the number of revolutions can directly influence the mechanism's performance. The other options do not correctly represent the number of mechanical revolutions associated with a 720-degree electrical rotation, thus clarifying the definitive answer.
