WebPhasor Diagrams and Phasor Algebra. Phasor diagrams present a graphical representation, plotted on a coordinate system, of the phase relationship between the voltages and currents within passive components or a whole circuit. Generally, phasors are defined relative to a reference phasor which is always points to the right along the x-axis. WebThus, our example circuit started out with a power factor of 0.705 lagging, and was corrected to a power factor of 0.999 lagging. REVIEW: Poor power factor in an AC circuit may be “corrected”, or re-established at a value close to 1, by adding a parallel reactance opposite the effect of the load's reactance.
