General Procedure For Solving Poisson's Or Laplance's Equation
The Following procedure can be used in solving boundary value problem using Laplance's or Poision's equation:
1. If ƿv = 0
we use Laplance equation and if not (ƿv ≠ 0 ) we solve poisson's equation for a given problem.
Consider situations:
If V is only a function of one variable then direct integration will used and if V is a function of more variables the method used will be the method of sepration.
While using the above procedure the solution may not be unique but it contains a number of constants.
2. A numbers of boundries would be given and these boundary conditions are applied to obtian the values of the problems.
3. Substituting the value of constant in the solution, a unique solution of problem is obtained.
4. After obtaining the value of V, to find the value of E, D, J we use
(a) To find E :
(b) To find D :
use D = ϵ E
(c) To find J :
5. Find the charge Q if needed by using the
6. The capacity of two conductors can be found using
7. The resistance of an object can be found using
