Watch the video above to learn the basics of power factor for a single-phase equivalent circuit, including phasor diagram and power triangle relationships.

*Make sure to watch in HD! (Click the gear icon in the lower right-hand corner of the video player).

In the first example, we go over an example using 120V for the single-phase applied voltage and total connected impedance of Z = 5 + j3 Ω and show every way that power factor can be calculated.

In the second example we keep the voltage the same but use a total connected impedance of Z = 5.83 Ω to explain unity power factor (PF = 1).
