No frogs were injured in the production of a voltaic pile. When Luigi Galvani's experiments with "animal electricity" were published , Volta began experiments that led him to theorize that animal tissue was not necessary for conduction of electricity.
Proof of this theory was the batt ery, which Volta invented in He built in the first electrical pile, or batt ery: a series of metal disks of two kinds, separated by cardboard disks soaked with acid or salt solutions. This is the basis of all modern wet-cell batt eries, and it was a tremendously important scientific discovery, because it was the first method found for the generation of a sustained electrical current. Volta built different piles using thirty, forty or sixty elements.
This enabled him to study the action of the pile on the electric fluid, depending on the number of elements, and he confirmed that the electric shock increased in intensity with the number of elements used in the pile. Between and , Volta discovered and isolated methane gas.

Proof of this theory was the battery, which Volta invented in He built in the first electrical pile, or battery: a series of metal disks of two kinds, separated by cardboard disks soaked with acid or salt solutions.
This is the basis of all modern wet-cell batteries, and it was a tremendously important scientific discovery, because it was the first method found for the generation of a sustained electrical current.
Volta built different piles using thirty, forty or sixty elements. This enabled him to study the action of the pile on the electric fluid, depending on the number of elements, and he confirmed that the electric shock increased in intensity with the number of elements used in the pile. After a few years, he switched gears and began working with chemistry projects. Volta was the first person to discover and isolate the compound methane.
Putting the two sciences together, he created the voltaic pile, a very early Battery An electric battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell contains a positive terminal, or cathode, and a negative terminal, or anode. Electrolytes allow ions to move between the electrodes and terminals, which allows current to flow out of the battery to perform work. The Voltaic Pile consisted of discs of copper and zinc separated by discs of paper or cardboard soaked in salt water.
When Volta closed the circuit, electricity flowed through the pile. What transpired after his groundbreaking invention is quite ironic. On his father's side he had three uncles. One was a Dominican, one a canon, and the other was an archdeacon. On his mother's side though, the family had more of a leaning toward the law.
The young Alessandro Volta started his education at the school of rhetoric in Como. However shortly after he started there, when Volta was only seven years old his father died. It was said that his father was more accomplished at spending money than making it.
In fact Volta said in later years that when his father died he left a small dwelling worth 14 lira, and a debt of 17 lira. Then, five years after his father's death his uncles took charge of his education. Initially they sent him to a Jesuit college, but later they changed the course of his education, moving him elsewhere.
It was during this period that a friend named Giulio Cesare Gattoni provided books and guidance to help his study of electricity. His uncles had decided it would be best for him to study the law but his interest in the natural sciences was so keen that they allowed him to follow his interests and take up career in physics and chemistry.
Volta became very absorbed in his studies and from the age of about 20 Volta studied science more formally. In particular he took an interest in electricity. 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.
