A few remarks on the analysis of energy transfer through any periodic current and voltage waveforms

Numerous publications point out that each of the so far presented proposals how to describe power states has some defects, they all lack the physical interpretation or the universal character. Yet, the application of a given power theory to analyze the electric circuit was not preceded by the proof of the rightness of such a procedure in relation to the character of this circuit. The authors of this paper seek the answer to the question whether a given power theory can be successfully applied in the analysis of both linear and non-linear circuits.
