Analysis of the electric current distribution in a three-layer conductive structure

The paper presents an analytical model allowing to investigate the electric current distribution in a three-layer conductive structure. The proposed model takes into account the characteristics of the three conductive layers and the transient resistances between them. Expressions for the current distribution and electric potential variation along the structure, as well as its total resistance are obtained. In addition, quantitative estimates showing the features of the electric current redistribution between the layers with alteration of the layers parameters are presented.
