As the author of the CPC-based power theory I would like to recognize Drs. Jeltsema’s and van der Woude’s attempts aimed at formulating that theory in the time-domain, as presented in Ref. . The CPC-based power theory was originally formulated in the frequency-domain, meaning with the use of a concept of harmonics and admittances for harmonic frequencies. Equivalent formulation of that theory in the time-domain would positively contribute to strengthening its fundamentals. Power theory of electrical systems is developed mainly for cognitive reasons: we would like to understand physical phenomena that accompany energy transfer. It is also developed for practical reasons: we would like to know how undesirable phenomena that accompany energy flow could be suppressed. The adjective “physical” in the name “Currents’ Physical Component”, (CPC), has therefore, a crucial importance. It means that each current component in the CPC-based power theory can be associated with a distinctive physical phenomenon in the circuit that can be observed by measurement. In this paper we will investigate if the current decomposition presented in Ref.  can be regarded as decomposition into currents’ physical components in the time-domain and its cognitive merits.
