Concept in Definition ABC

The ampere, also called amp, is theUnit from intensity from electric current constant, charge per unit of time that a material travels, which, staying in this way, in two conductors parallel, straight, of infinite length, of circular section and located one meter from each other in a vacuum, produces a force equal to 2 × 10-7.

As a consequence, the ampere is an integral part of the basic units in the System International of Measures as is the case with the meter, the second and even the kilogram and has received such a name in honor of André-Marie Ampere, a French mathematician and physicist which gained enormous relevance in the 19th century, after, for example, discovering the mutual actions between electric currents, demonstrating, without a doubt, what We mentioned earlier that two parallel conductors through which a current circulates in the same direction, will inevitably attract each other, on the other hand, if the senses of the current are opposite, they will repel each other.

On the other hand, the symbol with which the ampere or ampere is represented is the lyrics uppercase a (A), This is so because in the units established by the International System of Measurements, if the unit has been named with the name proper of an individual, such is the case of the ampere, the symbol will be the first letter of the proper name in question and it will be written in capital letter.
