Effective method for calculating of electric capacitance

An analytical method for calculating of an electric capacitance is proposed. The method is applicable to a wide class of secluded plates. The proposed method is based on using fictitious charge distribution along the surface of a body which substitutes a conductor. As a potential of a conductor its value in one characteristic point is taken. The sign of an error which is permissible for determining approximate conductor capacitance values is recommended. Quantitative results are compared with data obtained by means of existent methods. That made it possible to confirm a significant increase in the accuracy of a capacitance calculation with the help of the proposed method.
