In
this article I investigate on the origin of the idea of cycle in
S.
Carnot's
Theory according to hypothesis about analogy to the electric circuit of
Volta
’s
Pile. I perform, at first, a historical analysis (also of fundaments) of
the Réflexions sur la Puissance Motrice du feu (interpreted by
means of non-classical logic) to show the steps of the book in which S.
Carnot makes reference to
Volta
’s
Pile. Then I continue with a comparison, (still from the point of view of
their fundaments) between Sadi Carnot’s theory of the thermodynamics and
the electricity one. Without having the ambitious pretension to be
exhaustive, I will try an analogy between S. Carnot’s cycle and the
electric current cyclical path I in Volta’s Pile, which current I (among
two potential) corresponds to the flow of the caloric one between the two
thermostats in S. Carnot’s heat
machine. In more, I will introduce some cases in which, as in the
comparison between the
Volta
’s
Pile and S. Carnot’s thermodynamics is worth an analogy between electric
phenomenons and heat motive
power (as Mach’s work). Particularly I will compare this analogy to
Schmid and Fuchs works that, which – in the end of the years' 80-,
have tried to build a general analogy between electricity and
thermodynamics.
