The ampere is a unit that refers to the intensity of the electric current.
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 straight conductors one meter apart in a vacuum, with a circular section that is negligible and arranged in parallel, it generates a force in both conductors of infinite length. corresponding to two ten millionths of a newton 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 to mention that it shaped a classification of sciences that left its mark.
The ampere, a basic unit
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 number of amperes is not linked to the level of electric charge: the columbium is the derived unit whose definition is related to the amount of charge that an electric current of one ampere displaces in one second. The ampere, thus, indicates the average value of one columbium of charge per second.
The device that measures the amperes of electric current is called an ammeter . This instrument, when connected to an electrical circuit, reveals how many amperes the current has in circulation, thus reflecting its intensity.
The ammeter is a device that measures the amperes of an electric current.
An app for phones and tablets
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 to measure the charge and discharge current of the battery of those devices that have the Android operating system.
It is a way for the user to clear up doubts when they suspect that there is a problem because the battery has been charged too quickly.
«The memoirs of Amperio Felón»
It is curious to remember that scientific terms such as the ampere in question obtained a lot of 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 . It starred an evil witch, called Witch Breakdown , and some funnier and good beings called electrogoblins. Both it and these were surrounded by cables, voltages, electricity ...
Precisely one of its many episodes was titled "The Memoirs 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 have no regrets."
