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 Manzoni Alessandro Manzoni Alessandro Francesco Tommaso Antonio Manzoni (; 7 March 1785 – 22 May 1873) was an Italian poet and novelist. He is famous for the novel "The Betrothed" (orig. ) (1827), generally ranked among the masterpieces of world literature. The novel is also a symbol of the Italian Risorgimento, both for its patriotic message and because it was a fundamental milestone in the development of the modern, unified Italian language. Manzoni also sat the basis for the modern Italian language and helped creating linguistic unity throughout Italy. He was an influential proponent of Liberal Catholicism in Italy. Manzoni was
