1.1 Helmholtz's theorem. Duality of voltage and current reducers
Consider a passive linear network accessible from n terminals. Let two of its successive states be defined by terminal potentials and currents (figure
1
), with an asterisk distinguishing the second state from the first. Helmholtz's reciprocity theorem is expressed by the relation :
