## Poisson’s and Laplace’s Equations

Poisson’s Equation (Equation 5.15.5) states that the Laplacian of the electric potential field is equal to the volume charge density divided by the permittivity, with a change of sign. Note that Poisson’s Equation is a partial differential equation, and therefore can be solved using well-known techniques already established for such equations.

The Poisson and Laplace Equations

As we have shown in the previous chapter, the Poisson and Laplace equations govern the space dependence of the electrostatic potential. The general form of Poisson’s equation

5.6 Solutions to Poisson’s Equation with Boundary Conditions An approach to solving Poisson’s equation in a region bounded by surfaces of known potential was outlined in Sec. 5.1. The potential was divided into a particular part, the Laplacian of which balances -/ o throughout the region of interest, and a homogeneous part that makes the sum of the two potentials satisfy the boundary conditions.
