This lecture covers the application of the image charge concept to calculate the electric field, induced charge density, and total induced charge on the surface of a conductor. The slides illustrate the process step by step, starting with the concept of a point charge above an infinite plane conductor and progressing to the quantification of induced charges using Laplace's equation. The lecture emphasizes the relationship between image charges and neutral conducting surfaces, providing a detailed analysis of the E-field distribution and charge density. By the end, the total induced charge is derived, showcasing the practical implications of the theoretical framework presented.
