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
Alessandro Cruto the rest of his life between his family and his old laboratory. He continued his experiments on the accumulation of atmospheric energy and the invention of a toy called "mosca elettrica" ("electrical fly"). Cruto died, almost forgotten by all, in 1908. Alessandro Cruto Alessandro Cruto was an Italian inventor, born in the village of Piossasco, who created the incandescent light bulb. Son of a construction foreman, he attended the school of architecture at the University of Turin, while also attending Physics and Chemistry lectures with the dream of crystallizing carbon to obtain diamonds. In 1872 he opened a small workshop
