Abstract

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 ís Pile. I perform, at first, a historical analysis (also of fundaments) of the Rťflexions 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 ís Pile. Then I continue with a comparison, (still from the point of view of their fundaments) between Sadi Carnotís theory of the thermodynamics and the electricity one.

Without having the ambitious pretension to be exhaustive, I will try an analogy between S. Carnotís cycle and the electric current cyclical path I in Voltaís Pile, which current I (among two potential) corresponds to the flow of the caloric one between the two thermostats in S. Carnotís heat machine. In more, I will introduce some cases in which, as in the comparison between the Volta ís Pile and S. Carnotís thermodynamics is worth an analogy between electric phenomenons and heat motive power (as Machís work). Particularly I will compare this analogy to Schmid and Fuchs works that, which Ė in the end of the years' 80-, have tried to build a general analogy between electricity and thermodynamics.
