Phasor Algebra Explained (cont.) R I R (t) + V R (t)-Vcos( t) The Impedance of a Resistor is not frequency dependent, purely real and positive. Since it is purely real, it is called “Resistance”

A phasor, can be resolved into two components along two axis at right angles to each other. It is preferable and convenient to resolve it along X-axis and Y-axis. In symbolic form, a phasor is
