![]() Remember that phasors are used only when the frequency is the same. The phasors are used while comparing and performing mathematical operations on AC quantities. ![]() The magnitude of the phasor represents the magnitude of the quantity and the angle with the X-axis shows the phase angle. The direction of the phasor shows the angle of a sinusoidal waveform when it passes through the vertical axis. Phasor representation of an AC quantity is a counter-clockwise rotating vector originating from the origin of XY-axes (zero points) in a specific direction. ![]() Phasor arithmetic follows the rule so f phasor algebra. To work with a large amount of AC parameters waveforms, a simple representation can be introduced to differentiate among their magnitude and phase angle is called Phasor Representation of AC circuit analysis. The time-domain representation of different waveforms can be more intuitive but tedious in the case of multiple AC quantities and more data operation. When comparing it with another AC quantity (AC voltage, current, power, etc.), an effect of leading or lagging can be seen in time domain waveform. ![]() An alternating current waveform having a specific frequency. ![]()
