Dual nullator-norator networks

It is proved rigorously that the dual of a uniquely solvable planar network composed of a finite number of two-terminal elements such as nonzero linear impedances, independent voltage and current sources, and equal numbers of nullators and norators is also uniquely solvable. In particular, this enriches the class of nonlinear resistive circuit structures possessing a unique solution. A dual version of Tellegen´s famous theorem for nullator-norator multiports is also given
