Solution of the Electrodiffusion Equations in the Quasi-Stationary Approximation

The electrodiffusion equations are solved together with the equation for the current running through the boundary of the examined system with the environment. The complete system of equations allows the volt-ampere characteristic of the system to be obtained for an arbitrary time dependence of the external potential. The procedure of finding the first-order approximation is developed to solve the system of electrodiffusion equations.
