Capacitance and Dielectrics: Fundamentals

This lecture covers the fundamental concepts of capacitance and dielectrics, including the application of conductors with static charges, polarization of matter, alignment of dipoles in an electric field, and Gauss's law in the presence of dielectrics. It explains the definition of capacitance, energy stored in capacitors, and energy density. The lecture also discusses technical capacitors containing dielectrics for performance enhancement, the polarization of insulators by electric fields, the concept of electric dipole moment, and the mechanisms of polarization in materials. By the end, students will understand the role of dielectrics in capacitors and the various mechanisms through which polarization occurs.
