Dielectrics and Capacitance

This lecture covers the concept of dielectrics, a special class of materials that can be polarized by an applied electric field, leading to the development of dipole moments. The instructor explains how the potential function arises from these dipole moments, discussing the polarizability of materials and its temperature dependence. The lecture also delves into the evaluation of the functionality and performance of capacitors based on dipole moments, emphasizing the importance of considering the alignment of dipole moments with the electric field. Various examples of molecules with permanent electric dipole moments are presented to illustrate these concepts.
