Effect of Charge on Dielectric Polarization in Different Material Media

C. P. Ukpaka, C. Ahiakwo

Abstract


An investigation was conducted to demonstrate the effect of charge on dielectric polarization in different material media. The dielectric media considered in this study are a vacuum, polyethylene, water and barium titanate in a simple plate capacitor. The contributing factors on the effect of charge on dielectric polarization include the type of material used, energy stored, voltage and capacitance, separation between plate, size, dielectric constant, and area. The research work revealed that the high dielectric constant is a function of capacitor size, and the higher the dielectric constant, the smaller the capacitor size. Evaluation analysis on the functional parameters and coefficients for separation between plates at a range of 0.01–0.04 cm, 4 × 10-5 charge, potential of 5000–10,000 voltage, 4 × 10-9 capacitance, and initial permittivity of 8.85 × 10-14, as well as each dielectric constant parameters for vacuum, water, polyethylene and barium titanate are performed . It is observed that the charge influences the degree of dielectric polarization of material as well as the area and size.
