Lecture
This lecture covers the calculation of the electric field strength outside charged conductors, focusing on the impact of areal charge density and absolute charge. It also delves into the application of geometry-dependent capacitance, including pressure sensors and voltage detection. Additionally, it discusses the relationship between capacitance and dielectrics, alignment of dipoles in an electric field, and Gauss's law in the presence of dielectrics. The lecture concludes with an overview of energy and energy density stored in capacitors through a variation of charge on a plate capacitor.
