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?
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:
Electrostatic charges and forces problems are presented along with detailed solutions. Problems. Problem 1: What is the net force and its direction that the charges at the vertices A and C of the right triangle ABC exert on the charge in vertex B?
Electrostatics in integral and differential form. 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.
Capacitor in series and parallel: Solved Example Problems. EXAMPLE 1.22. Find the equivalent capacitance between P and Q for the configuration shown below in the figure (a). Solution. The capacitors 1 µF and 3µF are connected in parallel and 6µF and 2 µF are also separately connected in parallel.
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
