Tema maximum entropy production; Kirchhoff’s voltage law
 
Opis The standard derivation of Kirchhoff’s voltage law is based on the assumption that the first law of thermodynamics (sum of products of applied EMF’s and corresponding currents = heat dissipation) is satisfied within each loop. In contrast, we start from the fact that first law of thermodynamics applies globally to the electric circuit as a whole. It is then shown that Kirchhoff’s voltage law may be derived as an extremum of the system entropy production constrained by
the first law applied globally, and that the extremum is a maximum. Thus the stationary distribution of currents in a linear electric circuit is governed by the principle of maximum entropy production.
Uobičajeni izvod Kirchhoffovoga zakona za električnu petlju temelji se na pretpostavci da prvi zakon termodinamike (zbroj umnožaka narinutih elektromotornih sila i odgovarajućih struja = proizvedenoj toplini) vrijedi za svaku petlju. U ovom radu Kirchhoffov zakon za električnu petlju izvodi se pomoću principa maksimalne proizvodnje entropije, uz uvjet da prvi zakon termodinamike vrijedi za čitavu linearnu mrežu. Na taj način pokazuje se da se razdioba stacionarnih struja podvrgava principu maksimalne proizvodnje entropije.
