Dielectrics and Capacitors

This lecture explores the response of dielectric materials to an electric field, focusing on non-conductive materials like glass and plastic. It delves into the concept of permittivity, which characterizes a material's response to an electric field, and explains how different materials exhibit varying polarization behaviors. The lecture also covers the calculation of capacitors filled with dielectric materials, emphasizing the relationship between electric flux density, electric field, and permittivity. Through a detailed example involving a capacitor with two different dielectric materials, the instructor illustrates how to calculate electric field, electric flux density, and voltage across the capacitor.
