Anno XXVI - n.3 - luglio/settembre 1993 Concetti, esperimenti e pregiudizi: la lunga via verso la legge di Ohm. (Traduzione da Naturwissenschaften im Unterricht PHYSIK/CHEMIE n. 50, dicembre 1989, a cura di A.M. Fichera)
From 1775 to 1826 Ohm’s Law was gradually approached through the investigations of many researchers, stating with Cavendish. This article discusses the main experiments and the evolution of the underlying ideas, among which the concept of internal resistance of electrical generators eventually proved itself essential to Ohm’s discovery.

Anno XXXIII - n.1 - gennaio/marzo 2000 Confronto fra due apparecchiature commerciali per la misura della velocità della luce
In the research shown in this article the speed of the light in the air was determined by two different methods and by the use of the instruments provided by Leybold for both the experiments. In both the experiments we indirectly measured the time taken by a light beam to cover fixed distance. […]
Anno XLII - n.2 - aprile/giugno 2009 Confronto tra l’efficienza di un riscaldatore elettrico a effetto Joule e di una pompa di calore a effetto Peltier
The experimental comparison of an electric heater based on the Joule effect with a Peltier effect heat pump shows that the second device is the most effective of the two. […]
