When was alessandro volta born and died
A museum in his hometown, the Voltian Temple, was named after him and showcases some of the instruments he utilized to conduct experiments. A few meters from Lake Como is the Villa Olmo, which houses Voltian Foundation, a non-governmental organization that sponsors scientific activities. Volt is the unit of electromotive force, or dissimilarity of potential which inflicts a current of a single ampere to travel via a resistance of a single ohm. Photovoltaic are systems that transform light into electricity.
While his invention made him popular across Europe, Volta preferred a quiet life, and later gave up much of his research. He spent his last moments living in a country home in the town of Como, where he died in , at the age of Your email address will not be published.

Early Life Alessandro Volta was born in to a wealthy family and a strict Christian home.

He also boldly corresponded with many of the leading scientists of the day. In when he was just 18 years old, he corresponded with the eminent French physicist and electrical experimenter, the Abbe Antoine Nollet in Paris. Later he wrote to Giovanni Battista Beccaria, professor of physics at the University of Turin and the foremost Italian experimenter in electrostatics.
In many of these letters he showed a considerable degree of insight into the phenomenon of electricity that was just beginning to be understood. Volta even published some papers. His first was in , and was entitled "De vi attractiva ignis electrici. He performed his duties so well that in the following year he was appointed professor of experimental physics.
It was whilst he was at Como that he made some important discoveries. The first of Volta's discoveries occurred in when he invented the electrophorus, an early form of electrostatic generator. In its original form Volta's new device consisted of a cake of resin, wax, or other non-conducting substance placed between two metal plates.
The resin rested on the lower plate and the upper plate had an insulated handle attached to its centre that permitted it to be lifted from the resin cake. The upper metal plate was then removed and the upper surface of the resin was charged by friction. The upper plate, held by the insulated handle, was placed on the resin cake and, by touching the top plate with a finger, the charge was drawn off to ground.
On lifting the upper plate, it would thus be charged by induction. At this time in history electricity and chemistry were considered to be very closely related. Hydrogen, or as it was called then, "inflammable air" had been isolated in , and ten years after this in , Volta discovered a new gas that we know as methane today.
In his researches, Volta became intrigued by the many different kinds of "air" that could be found, one of which could be seen bubbling from lakes and ponds. Although he noted that methane was less explosive than hydrogen, he used it in what was termed an inflammable air pistol that he fired using an electric spark.
This contraption was surprisingly effective firing a lead ball and denting wood at a distance of 5 metres. His discovery of methane in particular brought him considerable renown and as a result he received a travel grant from the Austrian government that ruled northern Italy at this time. This enabled him to travel to other countries to meet other notable scientists. The first of his travels began in early September with visits to fellow scientists in Switzerland, Alsace and Savoia.
He travelled widely and this enabled him to meet with other scientists and discuss their work together. With the rise of Volta's fame came the offer of a university chair.
In he was appointed to the post of professor of experimental physics at the University of Pavia. This was a position that Volta held for nearly 40 years. Volta's most ground-breaking work was that lead to the development of the first battery. The roots of this work can be traced back to some investigations performed by a fellow Italian and friend of Volta.
He discovered that when an electrical discharge occurred near a frog's leg whilst it was being dissected, the discharge made its leg twitch. The Italian professor made many further researches and this lead to his discovery that when two dissimilar metals were placed on the leg, and electric current was generated.
For many years it was believed that this was a new form of electricity that they called "animal electricity". Volta himself performed many experiments to investigate the phenomenon further. He even started to place dissimilar metals on his tongue and close to his eye with various effects. However as he undertook further experiments he became more convinced that the electricity was being generated by the two dissimilar metals separated by a solution such as brine.
Galvani, though continued to defend his idea of animal electricity. Volta was the most vocal doubter, and embarked on a series of experiments to develop a different explanation for the strange phenomena. The type of electrical activity theorized by Volta came to be known as metallic electricity. The disagreement between Volta and Galvani became a significant matter of debate at the time, with opposing camps aligning themselves with one scientist or the other.
Both, however, were partly correct: muscular contractions are stimulated by electricity as suggested by Galvani and contact between dissimilar metals can produce a current as proposed by Volta. While attempting to prove his own theory, Volta experimented with various metals and electrolytes, eventually producing the voltaic pile.
The pile consisted of a series of discs of zinc and copper later other metals were used arranged vertically and separated by pieces of cloth or cardboard soaked in an acid or salt solution. Glass rods provided support to the discs, the number of which Volta varied to produce stronger or weaker charges. In Volta announced his invention of a device that could continuously generate an electrical current, and the voltaic pile was enthusiastically received. In , he retired to a family estate in the country.
He died on March 5, In , the term volt was officially adopted in his honor to designate the unit of electric potential and electromotive force.
