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
University of Pavia that immediately preceded the Unification (1859–66). During the following centuries, through periods of both adversity and prosperity, the fame of the University of Pavia grew over the last years due to the large number of applicants. Throughout its history, the university has benefited from the presence of many learned men and distinguished scientists who wrote celebrated works and made important discoveries: mathematician Girolamo Cardano (born in Pavia, 1501–76), physicist Alessandro Volta (Pavia chair of natural philosophy 1769-1804), poet Ugo Foscolo (chair of Italian eloquence 1809-10). Three Nobel Prize winners also taught in Pavia: physician Camillo Golgi (at Pavia from 1861),
