What is ampere?

What Does ampere Mean

The term ampere is synonymous with ampere : a unit of the International System that reflects the intensity of electric current . One ampere is equivalent to the intensity of the current when, when passing through two rectilinear conductors one meter apart in a vacuum, with a negligible circular section and arranged in parallel, it generates a force in both conductors of infinite length. corresponding to two ten millionths of newtons per meter of conductor.

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 died on June 10, 1836 in Marseille . Ampère postulated the theoretical foundations of electromagnetism, developed the electromagnet with another scientist named François Arago, and created the electric telegraph .

It is important to know that among the entire set of actions that he carried out within the scientific field, he also stood out for having developed the law of thermodynamics or for having created the galvanometer. Not forgetting either that it shaped a classification of the sciences that left its mark.
The ampere, like the kilogram, the second and the meter, is part of the so-called basic units (they do not depend on other units). The amount of amperes is not related to the level of electrical charge: columbium is the derived unit whose definition is related to the amount of charge that an electrical current of one ampere displaces in one second. The ampere, in this way, indicates the average value of one columbium of charge per second.
The device that measures the amperes of electrical current is called an ammeter . This instrument, when connected to an electrical circuit, reveals the amount of amperes in the circulating current, thus reflecting its intensity.
We cannot ignore that within the vast number of applications that exist today for mobile phones and tablets, there is one called Ampere. Its function is none other than to measure the charging and discharging current of the battery of those devices that have the Android operating system.
It is a way for the user to get out of doubt when he suspects that there is a problem because the battery has been charged too quickly.
It is curious to remember that scientific terms such as the ampere that concerns us obtained much prominence in an old children's television program called “La Bola de Cristal”, directed by Lolo Rico and which remained on the air in Spain between 1984 and 1988. an evil witch, called Witch Avería, and by some more fun and good beings called electrobuendes. Both she and these were surrounded by cables, voltages, electricity ...
Precisely one of its many episodes was entitled "The memories of Amperio Felón." In the east, the aforementioned 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."
