The term ampere is synonymous with amp : a unity of the International system which reflects the electric current intensity . An ampere is equivalent to the intensity of the current when, when passing through two rectilinear conductors distant from each other to a meter in a vacuum, with a circular section that is negligible and arranged in parallel, it generates in both conductors of infinite length a force corresponding to two ten millionths of newton per meter of driver.

The concept of ampere comes from the name of André-Marie Ampère , a physicist and mathematician born on January 20, 1775 in the french city of Lyon and deceased on June 10, 1836 in Marseilles . Ampère postulated the theoretical foundations of electromagnetism, developed the electromagnet with another scientist called Francois Arago and created the Telegraph electric.

It is important to know that among all the set of actions carried out within the scientific field, he also stood out for having developed the law of thermodynamics or for having created the galvanometer. That without forgetting that it shaped a classification of sciences that left its mark.

The ampere, like the kilogram, the second and the meter, is part of the calls basic units (do not depend on other units). The amount of amperes is not linked to the level of electric charge: it is the columbium the derived unit whose definition is related to the amount of charge that an electric current of one amp displaces in a second. The ampere, thus, indicates the value half a columbium of load per second.

The device that measures the amps of the electric current is called ammeter . This instrument, when connected to an electrical circuit, reveals how many amps the current has in circulation, thus reflecting its intensity.

We cannot ignore that within the large number of applications that currently exist for mobile phones and tablets, there is one called Ampere. Its function is none other than measuring the battery charge and discharge current of those devices that have the Android operating system.

It is a way that the user can leave doubts when he suspects that there is a problem because the battery has been charged too fast.

It is curious to remember that scientific terms such as the one in which we are concerned gained a lot of prominence in an old children's television program called “La Bola de Cristal”, directed by Lolo Rico and that remained on the air in Spain between 1984 and 1988. It was starred by an evil witch, called Witch Breakdown, and for more fun and good beings called electroduendes. Both she and these were surrounded by wires, voltages, electricity ...

Precisely one of his many episodes was titled "The Memories of Amperio Felón". In the east, the said witch became the owner of the television network and made statements such as "anodes, cathodes and filaments ... I am bad and I do not regret it."
