Phasor diagram

A phasor diagram visually represents electrical signals that vary periodically, like alternating current (AC). It uses vectors (arrows) in a circle to show both the magnitude (strength) and phase (timing) of these signals. The length of the arrow indicates the signal's amplitude, while the angle shows its phase difference relative to others. This helps engineers analyze how different AC signals interact, such as in power systems or electronic circuits, making complex oscillations easier to understand and visualize their relationships in a clear, geometric way.
