No one can say since the time humans discovered what was later called “Electricity.” The evidence we have is that, 600 years before Christ, this phenomenon was observed by the Greek philosopher “Thales of Miletus.” It was the first to discover the attraction and repulsion of objects such as cloth or leather, rubbed on a piece of “a mbar yellow.” a This is a resinous substance, which in Greek is called “ELEKTRON”, this gave rise to the name of the atomic particle “ELECTRON”, and the term “electricity.” Then later. it was discovered that not only had the property elektron attract small particles, when they were subjected to rubbing with glass, silk, cloth, etc. Given the relationship with the phenomenon of elecktron, was adopted the term “electrified” indicating that a body had acquired the same properties. Who has not rubbed a comb in his hair and then bring it to a small piece of paper?. All certainly have done and observed as the piece of paper attached to the comb, this is “static.” The intensity of an electric current is expressed in “coulomb per second.” A “AMP” is equivalent to a Coulomb per second and his name is in honor of the French mathematician and scientist “Andre Marie Ampere (1775-1836). Electrodynamics was who devised and invented the electromagnet and telegraph. Resistance: An” Ohm is the resistance that has a driver when applying an electrical voltage of one volt at the ends, it produces a stream of “Ah.” Voltio: electric pressure Determined to send an electric current through a conductor. A volt is the pressure required to cause a current of one coulomb per second is one ampere through a conductor that provides a resistance of one ohm.

It is also called “electromotive force” (fem.). The name is Volt after the Italian physicist Alessandro Volta (1745-1827). Alessandro Volta invented the electric battery that bears his name.
