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
Volta Cinematograph Volta Cinematograph The Volta Electric Theatre (later renamed the Lyceum Picture Theatre) was a film theatre in Dublin and was Ireland's first dedicated cinema. The site at 45 Mary Street was later demolished and is occupied today by a department store. In the early 1900s, demand for moving pictures was fierce and cinemas were springing up all over the world. After visiting Trieste, the writer James Joyce was determined to bring a cinema to Ireland, so after receiving the backing of his Italian friends, he set up the Cinematograph Volta on Mary Street. It opened its doors on 20 December
