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 Vespignani Alessandro Vespignani Alessandro Vespignani is an Italian-American physicist, best known for his work on complex networks, and particularly for work on the applications of network theory to the spread of disease, applications of computational epidemiology, and for studies of the topological properties of the Internet. He is currently the Sternberg Family Distinguished University Professor of Physics, Computer Science and Health Sciences at Northeastern University, where he is the director of the Network Science Institute. Vespignani is serving in the board/leadership of a variety of professional associations, institutions and journals. Vespignani is author, together with Romualdo Pastor-Satorras, of the book "Evolution
