There were a few works on computation of capacitance in electrostatic problems using method of moments. Point matching method was introduced at first, which calculate charge distributions on planar conflicting surface divided into small rectangles. This method could be applied to limited geometry. For this, it was presented that a method dividing conductor surface into triangular area can be applied in plate objects. Point matching method was also used. In this paper charge distributions and capacitance are computed with rectangular and triangular area functions, and accuracy is investigated. Point matching and Galerkin's method are used for testing. When integrating, approximate and numerical method were carried out and the convergence was observed. Pulse function and impulse or pulse function for testing. When field and source points coincide, the integration was done analytically, by doing this sample results were obtained and generalized for numerical integrations. For example in applications, the convergence of solution was investigated for rectangular plate and capacitance was compared with that of circular disk which has exact value.
