Abstract

The use of power and energy functionals in the Hilbert space makes it possible to appreciate the energy equilibrium state attained in the quasi-stationary regime of electromagnetic fields at a certain moment. This paper deals with a demonstration of the principle of minimum energy for the electric and magnetic circuits in quasi-stationary regime. It is shown that the equilibrium state of a circuit represent a minimum energy state..
