Web21. apr 2006 · Electric field statistics inside the composites are also computed, and localized intensification factors in the range of three to eight times the applied field are predicted, with an incrementally linear growth in high-field probability with increasing filling fraction in the soft percolation regime. WebThe capacitance of a capacitor filled with a dielectric is greater than it would be in a vacuum. The effects of the dielectric on electrical phenomena are described on a large, or macroscopic, scale by employing such concepts as dielectric constant, permittivity, and electric polarization.
