Learn how to solve electrostatic problems. Overview of solution methods. Simple 1-D problems. Reduce Poisson’s equation to Laplace’s equation. Capacitance. The method of images. Overview. Illustrated below is a fairly general problem in electrostatics. Many practical problems are special cases of this general problem. Where to start?
So for V, we have only one 2 nd order DE to solve, but if we approach the problem using electric field q, we end up with two equations: · q L Ù, H q L Ù In general, there are two major ways to solve the potential problems in electrostatic: (a) Solve as a source problem using integration, (b) Solve as a boundary value problem, using boundary
A simple problem. What is electrostatics? DC behavior – no time variation or waves. No magnetic field or currents. Study of the behavior of stationary electric charges and the resulting electric fields. Electrostatics can be formulated in an integral form.
Examples of Electrostatic Problems with Dielectrics Problem: Find (electric flux density), (electric field intensity), and (polarization) for a metallic sphere (radius a, charge Q), coated by a dielec-tric (radius b), and the charge densities at the interfaces. Solution: Use Gauss’ Law In region 0, In region 1, a < r < b:
