Explore the fundamentals of linear dielectrics and electric fields in matter, focusing on electrostatic potential calculations for a charged metal sphere surrounded by dielectric material. Learn about displacement field (D), polarization (P), bound charges (σ_b, ρ_b), and permittivity (ε) in spherically symmetric systems. Understand Gauss's law in dielectrics, susceptibility (χ_e), and the role of homogeneous materials in simplifying Maxwell's equations. Discover how dielectric properties reduce electric fields compared to conductors, surface charge distributions, and boundary conditions. Ideal for students studying electrostatics, materials science, or electrical engineering, with insights into dielectric behavior, electrostatic shielding, and applications in capacitor design or insulating materials.
