Plan • Maxwell’s Equations, Special cases • Static • Quasi-static • Time-harmonic • Wave • Electrostatics • Key Concepts • Gauss, Coulomb, Poisson & Laplace’s Equations • Battle Plan • Discrete (Point) Charges • Spherical Coordinate System • Continuous Charge Distributions • Line Charge • Cylindrical Coordinate System
Electrostatics: Key Concepts • Maxwell’s equations are decoupled What???
