Phasor Analysis

Phasor analysis is a method used in electrical engineering to visualize and analyze alternating current (AC) signals. It represents sinusoidal waveforms as rotating vectors (phasors) in a complex plane, where length indicates amplitude and angle indicates phase difference. This simplifies calculations involving multiple AC signals by converting time-based functions into steady-state vectors, making it easier to understand how signals add, compare, or interact. Phasor analysis is essential for designing and troubleshooting AC circuits, as it provides a clear picture of the relationships between voltage and current waveforms in systems like power grids and electronic devices.
