Voltage across the inductor's terminals. This is the reason that measurements with a voltmeter across an inductor are often reasonably independent of the placement of the test leads. The volt (symbol: ) is the derived unit for electric potential, electric potential difference, and electromotive force. The volt is named in honour of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, possibly the first chemical battery. A simple analogy for an electric circuit is water flowing in a closed circuit of pipework, driven by a mechanical pump. This can be called a "water circuit". Potential difference between two points
Italian unification landscapes, rural scenes, and military life during the Italian unification. In literature, lots of works were dedicated to Risorgimento since the beginning. The most known writer of Risorgimento is Alessandro Manzoni whose works are a symbol of the Italian unification, both for its patriotic message and because of his efforts in the development of the modern, unified Italian language; he is famous for the novel "The Betrothed" (orig. Italian: "I Promessi Sposi") (1827), generally ranked among the masterpieces of world literature. Vittorio Alfieri, was the founder of a new school in the Italian drama, expressed in several occasions his suffering
