Alessandro Giuseppe Antonio Anastasio Volta or Alessandro Volta Batteries Noted as the first inventor, was born in Como, Italy, and taught in the public schools there. In 1774 he became professor of physics at the Royal School in Como. A year later, he improved and popularized Electrophorus, a device that produces a static electric charge. promotion was so extensive that he is often credited with its discovery, although the engine operates in the same principle described in 1762 by Swedish professor Johan Wilcke.
Volta was an Italian physicist. He is especially known for developing the battery in 1800. He continued work of Galvani Luigi Galvani and prove that the theory of the shock effect of frog legs is wrong. In fact, this effect does not arise from a kind of 2 metal scalpel Galvani. Based on this opinion, succeeded in creating Battery Volta Volta (Voltac Pile). For his services, the unit of electric potential difference is called the volt.
In the 1776-1777 Volta studied the chemistry of gases. He discovered methane by collecting the gas from marshes. He designed an experiment such as the combustion of methane by an electric spark in a closed container. Volta also studied what we now call electrical capacitance, developing separate means to study both electrical potential (V) and charge (Q), and found that they are proportional to an object. This may be called Volta's Law of capacitance, and likely for this work the unit of electrical potential called the Volt.
In 1779 he became professor of experimental physics at the University of Pavia, he held the seat for nearly 25 years. In 1794, Volta married Teresa Peregrini, who raised three children, Giovanni, Flaminio and Zanino. In honor of his work, Volta was made count by Napoleon in 1810. Furthermore, he described the 10,000 Italian Lire (no longer in circulation) along with the famous sketch Voltaic Pile.

Volta began to learn about 1791, "power" of animals noted by Luigi Galvani when two different metals are connected in series with the frog's leg and each other. Volta realized that the frog's leg served as both an electrical conductor (the electrolyte) and as a power detector. He replaced the frog's leg by brine-soaked paper, and detected the flow of electricity in another way that he knew from previous studies. In this way he discovered the electrochemical series, and the law that the electromotive force (emf) of a galvanic cell, which consists of a pair of metal electrodes separated by an electrolyte, the difference between their two electrode potentials. This may be called Volta's Law of the electrochemical series.
In 1800, as a result of a professional disagreement over the galvanic response advocated by Galvani, he invented the voltaic pile, early electric battery, which produces an electric current is stable. Volta had determined that the most effective pair of dissimilar metals to produce electricity zinc and silver. Initially he experimented with individual cells in series, each cell a wine goblet filled with brine in which two different electrodes are dipped. Voltaic pile replaced the glass with cardboard soaked in salt water.
The battery made by Volta is credited as the first electrochemical cell. It consists of two electrodes: made of zinc, the other of copper. electrolyte is sulfuric acid or a mixture of salt water and salt water. electrolyte is in the form 2H + and SO42-. Zinc, which is higher than that of copper and hydrogen in the electrochemical series, reacts with negatively charged sulfate. (SO42-) ions-positively charged hydrogen ions (protons) capture electrons from the copper, forming bubbles of hydrogen gas, H2. This makes the zinc rod the negative electrode and a positive electrode of copper rod.
However, these cells have some disadvantages as well. It is not safe to handle, as sulfuric acid, even when diluted, is very dangerous. In addition, the strength of the cell decreases with time because hydrogen gas is not released, collecting only the zinc electrode surface and form a barrier between the metal and the electrolyte solution. Primitive cells are widely used in schools to demonstrate the laws of electricity and is known as a lemon battery.
Volta retired in 1819 the estate in Camnago, a frazione Como now called Volta Camnago after, where he died on March 5, 1827. He was buried in Camnago Volta . Volta legacy celebrated by Temple on the banks of Lake Como in the town center. A museum in Como, Voltian building, has been built in his honor and exhibits some original equipment he used to perform experiments. Standing near Lake Como Villa Olmo, which houses Voltian Foundation, an organization that promotes scientific activities. Volta conducted experimental studies and made the first discovery in Como. For his services, the unit of electric potential difference is called the volt.
