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
Abraham Bennet Abraham Bennet Abraham Bennet FRS (baptised 20 December 1749 - buried 9 May 1799) was an English clergyman and physicist, the inventor of the gold-leaf electroscope and developer of an improved magnetometer. Though he was cited by Alessandro Volta as a key influence on his own work, Bennet's work was curtailed by the political turbulence of his time. Abraham was baptised in Taxal, Derbyshire, the son of another Abraham Bennet, a schoolmaster, and his wife Ann "née" Fallowes. There is no record of him having attended university but he is recorded as a teacher at Wirksworth Grammar School as "MA".
