Abstract: In this paper, a new and general formula of capacitance of a capacitor with anisotropic dielectric shown by generalized orthogonal coordinate and inverse matrix of dielectric constant is derived by use of the displacement current, It provides a new and simpler method for computing capacitance of a capacitor. The formula has been checked by several practical examples. -
