What term describes the flow of current through one positive thrust followed by a negative flow?

The term that describes the flow of current through one positive thrust followed by a negative flow is referred to as a cycle. In the context of electrical current, a cycle represents one complete waveform, encompassing both the positive and negative phases of the wave.

When analyzing alternating current (AC), for example, the cycle outlines how the current changes direction—first flowing in a positive direction and then reversing to flow in a negative direction. This cyclical behavior is essential for understanding how various electrical systems function, including their operational characteristics and energy transfer.

While other terms like wave, period, and frequency relate to the characteristics of waveforms, they do not specifically indicate the completion of a positive and negative phase in the same way the term cycle does. A wave refers to the shape of the signal, period describes the duration of one complete cycle, and frequency indicates how many cycles occur in a specific timeframe, generally measured in hertz. Each of these terms plays a role in electrical engineering, but the completion of both directions of flow is best encapsulated by the term cycle.
