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 are based on different combination loads. Pure sinusoidal sine waves are displayed through a computer sound card, and the load phase angle between the fundamental components of the load voltage and current is calculated. This study highlights the importance of power factor in electrical engineering, aiming to enhance our understanding of how different loading conditions influence power efficiency and system performance. By evaluating various load combinations, we present insights on the practical implications of power factor variations, which can lead to significant cost savings in electricity charges and improved power quality. The findings are crucial for both academic research and practical applications in electrical systems.
