NON-SYMMETRIC FINITE NETWORKS: THE TWO-POINT RESISTANCE

Viera Čerňanová – Juraj Brenkuš – Viera Stopjaková

   An explicit formula for the resistance between two nodes in a network described by non-symmetric Laplacian matrix L is obtained. This is of great advantage eg in electronic circuit fault analysis, where non-linear systems have to be solved repeatedly. Analysis time can be greatly reduced by utilization of the obtained formula. The presented approach is based on the "mutual orthogonality" of the full system of left and right-hand eigenvectors of a diagonalizable matrix L. Simple examples are given to demonstrate the accuracy of this approach to circuit networks.

Keywords: electronic circuit, fault analysis, non-symmetric Laplacian matrix, resistance computation
