Web A Phasor Is A Special Form Of Vector (A Quantity Possessing Both Magnitude And Direction) Lying In A Complex Plane.
Consider the following differential equation for the voltage across the capacitor in an rc circuit And phase has the form: Specifically, a phasor has the magnitude and phase of the sinusoid it represents. Thus, phasor notation defines the rms magnitude of voltages and currents as they deal with reactance.
