How many directions does current flow during one cycle?

During one cycle of alternating current (AC), the electric current flows in both directions. This is a fundamental characteristic of AC, where the direction of the current periodically reverses, typically following a sinusoidal waveform. In one complete cycle, the current first flows in one direction and then reverses to flow in the opposite direction.

This behavior is essential for various applications, including the operation of motors and transformers, which rely on the changing direction of current to function effectively. Additionally, the period of the cycle defines the frequency of the current, often measured in hertz, which indicates how many complete cycles occur in one second.

In contrast, direct current (DC) flows in only one direction, which is why understanding the nature of alternating current is crucial for electrical work and applications. Therefore, recognizing that AC current flows in two distinct directions during one cycle is vital for those in the electrical field.
