• Electrostatic Fields and Gauss's Law: From Coulomb's Law to the Poisson EquationFrom Coulomb's law we define the electric field, prove Gauss's law in integral form by a solid-angle argument, derive div E = ρ/ε₀, and reach the Poisson equation.PhysicsElectromagnetismUndergraduateElectrostaticsGauss's lawCoulomb's lawPoisson equationVector calculus~29 min
