Alessandro Volta — of the electric cell

Alessandro (February 18, 1745 March 5, was a Lombard physicist known for the development of the first electric in 1800.


Alessandro a Lombard physicist, is known for his pioneering work in electricity. was born in Como and educated in the schools there. In 1775 he professor of physics at the Royal in Como; in the following year, he the electrophorus, an instrument that charges of static electricity.

In he applied himself to chemistry, atmospheric electricity and devising such as the ignition of gases by an spark in a closed vessel. In he became professor of physics at the of Pavia, a chair he occupied for 25 By 1800 he had developed the so-called pile, a forerunner of the electric which produced a steady of electricity.

In honor of his work in the of electricity, Napoleon made him a in 1810. A museum in Como, the Temple, has been erected in his and exhibits some of the original he used to conduct experiments. Lake Como stands the Olmo, which houses the Foundation, an organization which scientific activities. Volta out his juvenile studies and made his inventions in Como.

His great grandchild, Alessandro Volta, was the founder of Waldorf-Astoria needed]

Inventions and discoveries

In Volta improved and popularized the a device that produces a electric charge. His promotion of it was so that he is often credited its invention, although it had actually invented in 1764 by Swedish Johan Carl Wilcke[3] In he studied the chemistry of gases, methane, and devised experiments as the ignition of gases by an electric in a closed vessel. Volta studied what we now call developing separate means to both electrical potential V and Q, and discovering that for a given they are proportional. This may be Volta’s Law of Capacitance, and likely for work the unit of electrical has been named the volt. In he became professor of experimental at the University of Pavia, a chair he for almost 40 years. In 1794, married the daughter of Count Peregrini, Teresa, with he raised three sons.

Around 1791 he began to the animal electricity noted by when two different metals connected in series with the leg and to one another. He realized that the leg served as both a conductor of (we would now call it an electrolyte) and as a of electricity. He replaced the frog’s leg by paper, and detected the flow of by other means familiar to him his previous studies of electricity. In way he discovered the electrochemical series, and the law the electromotive force (emf) of a cell, consisting of a pair of electrodes separated by electrolyte, is the of their two electrode potentials. is, if the electrodes have emfs. the net emf is. (Thus, two identical electrodes and a electrolyte give zero net This may be called Volta’s Law of the series.

In 1800, as the result of a disagreement over the galvanic advocated by Luigi Galvani, he the voltaic pile, an early battery, which produced a electric current. Volta had that the most effective of dissimilar metals to produce was zinc and silver. Initially he with individual cells in each cell being a goblet filled with into which the two dissimilar were dipped. The electric replaced the goblets with soaked in brine. (The of cells, and thus the voltage it produce, was limited by the pressure, by the upper cells, that squeeze all of the brine out of the cardboard of the cell.)

In announcing his discovery of the pile, paid tribute to the influences of Nicholson, Tiberius Cavallo and Bennet.[4]

The Voltaic battery

The made by Volta is credited as the electrochemical cell. It consists of two one made of zinc, the other of The electrolyte is sulfuric acid or a mixture of salt and water. The exists in the form 2H+ and SO4 2-. The zinc, is higher than both and hydrogen in the electrochemical series, with the negatively charged ( SO4 ) The positively charged hydrogen start depositing around the and take away some of its This makes the zinc rod the electrode and the copper rod the positive

We now have 2 terminals, and the current flow if we connect them. The in this cell are as follows:

Zn — Zn2+ + 2e-


2H+ + 2e- — H2

The copper does not functioning as an electrode for the reaction.

this cell also has disadvantages. It is unsafe to handle, as acid, even if dilute, is Also, the power of the cell over time because the gas is not released, accumulating instead on the of the electrode and forming a barrier the metal and the electrolyte solution. So it is not and therefore, not a suitable choice.

In honor of his work in the field of Napoleon made him a count in in 1815 the Emperor of Austria him a professor of philosophy at Padua.

presenting his Voltaic Pile to 1796, Lombardy was ruled by From 1796 to 1815, came under Napoleon’s After 1815, Lombardy was again under Austrian Thus Volta was once a of the Emperor of Austria, later a of Napoleon and then later a of the Emperor of Austria again.

Tempio Voltiano, ComoHe was a correspondent of the Royal Society and was a fellow (FRS). He received the 1794 Copley Medal. He his invention of the Voltaic pile in 1800 in the Philosophical Transactions of the Society. He was in correspondence with in Austria, which ruled in his day, and in France. His 1800 was written in French.

Volta is in the city of Como. At the Tempio near Lake Como is a museum devoted to explaining his Count Volta’s original and papers are on display there. The along with his portrait, on Italian 10.000 lira before the introduction of the euro.

In an important electrical unit, the was named in his honor. There also been innovations and named after Alessandro including the Toyota Alessandro the Volta Crater on the Moon and in a technology company named loan origination platform
