Stored Coulomb Self-Energy of a Uniformly Charged Rectangular Plate

Figure 2

The Coulomb self-energy of a uniformly charged rectangular plate, , can be expressed in units of for in terms of a function, , where is a nonnegative dimensionless parameter. The value represents a uniformly charged square. The value represents a uniformly charged line with length, , in which a total charge, , is uniformly spread over its length. The values of parameter in the plot vary from to in steps of .
