Comparative study and analyzes the power factor variation due to loading effect

Abstract: Power factor is most important for all industrial as well as domestic sectors. In this research paper present the comparative study and analyzes the power factor variation due to loading effect. For this comparison we take different values of inductance, three different range of capacitor and two range of resistance and their total impedance is calculated. The calculated theoretical and practical values of power factor on the basis of different combination loads. Pure sinusoidal sine waves are displayed in computer through sound card and calculate the load phase angle between the fundamental components of the load voltage and current.
