Examination of the Change in the Power Factor Due to Loading Effect

Research work is carried out to examination of the change in the power factor due to loading effect. In this experiment, we are taking different values of inductance, one range of capacitor and two ranges 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.
