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
Memorial to Alessandro Valtrini case of Alessandro Valrtrini monument, a medallion-shaped portrait of Valtrini himself. Valtrini had been a wealthy donor during his lifetime. Three churches he had supported erected monuments to him, Il Gesù (where his body remained), Santa Maria sopra Minerva and the Bernini version in San Lorenzo in Damaso. He died in 1633. Francesco Barberini organised the Bernini commission in the late 1630s. Memorial to Alessandro Valtrini The Memorial to Alessandro Valtrini is a funerary monument designed by the Italian artist Gian Lorenzo Bernini in 1639, and executed by his workshop in the same year. It is situated in the church
