Active, reactive, and scattered current in circuits with nonperiodic voltage of a finite energy

A theoretical basis for describing the energy properties of circuits with nonperiodic voltage of finite energy is formulated. It is shown that the current in such a circuit can be decomposed into three orthogonal components related to three different phenomena that are responsible for the current value. This decomposition not only explains the energy properties of such circuits, but it also forms the basis for the source current minimization. Conclusions are drawn about measurements that are required for this purpose
