Szukana fraza: [Abstrakt = "The paper presents a description of polymer cylindrical samples of polymer and the construction and calculation of their three–dimensional percolation electric models \(percolation for the branch network\). The three–dimensional percolation electric models of polymer samples are the electrical circuits. The electrical circuits are composed of five square networks, arranged concentrically and connected together. Each network has branches of resistors or impedance \(appropriate compilation of resistors and capacitors\). The defined three–dimensional percolation model electric has been transformed into flat electric circuit and then adapted to the analysis in the PSpice software. In the analysis of electric circuit, according to the percolation theory, the randomly way of closing its branches has been applied. The simulation calculations of the polymer samples current were determined based on their three–dimensional percolation electrical models, the forcing voltage of a specific frequency and declaring relevant current analyzes in PSpice software."]
