Voltaic pile generates 0.76 V with a brine electrolyte. The voltages from the cells in the pile add, so the six cells in the diagram above generate 4.56 V of electromotive force. Voltaic pile The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. It was invented by Italian physicist Alessandro Volta, who published his experiments in 1799. The voltaic pile then enabled a rapid series of other discoveries including the electrical decomposition (electrolysis) of water into oxygen and hydrogen by William Nicholson and Anthony Carlisle (1800) and the discovery or isolation of the
Alessandro Scarlatti Alessandro Scarlatti Pietro Alessandro Gaspare Scarlatti (2 May 1660 – 22 October 1725) was an Italian Baroque composer, known especially for his operas and chamber cantatas. He is considered the founder of the Neapolitan school of opera. He was the father of two other composers, Domenico Scarlatti and Pietro Filippo Scarlatti. Scarlatti was born in Palermo (or in Trapani), then part of the Kingdom of Sicily. He is generally said to have been a pupil of Giacomo Carissimi in Rome, and some theorize that he had some connection with northern Italy because his early works seem to show the influence
