Electrical currents
are measured in a unit called amperes, which are abbreviated as "amps." There are two different designations that measure currents: direct currents (DC) and alternating currents (AC). Amperes are coulombs per second. Amperes are electrical current units that are part of the meter-kilogram-second system. A flow of one coulomb per second is equivalent to one single ampere.
History
The unit ampere (amp) was named after the French mathematician and physicist Andre Marie Ampere (1775-1836). Ampere formulated "Ampere's Law," a mathematical analysis of magnetic fields created by conductors that transmitted electrical currents.
Ampere's Law
This law states that magnetic fields existing in areas around electrical currents are proportional to electrical currents that operate as the sources. For any closed loop pathway, the total sum of the magnetic elements multiplied by the lengths elements (going in the direction of the length element) is equivalent to the permeability multiplied by the electrical current that is located inside of the closed-loop pathway.
Significance
The ampere, which measures electrical currents, measures the amount of electrons that go through any specific point in single-second intervals. Approximately 6 quintillion electrons that go through a specific point every single second make up one single ampere unit.
Equivalency
One coulomb is about equal to 6.24150948í--1018 electric charges carried by single protons (elementary charges), so therefore one amp is equal to about 6.24150948í--1018 elementary charges. Electrons, which are an example, glide past single boundaries in a single second.
Amps and Currents
One single ampere is the exact amount of electrical current that is created as a result of the strength and force of a single volt (electric potential difference units), acting with the resistance of one ohm (the "ohm" is a method for measuring the amount of resistance).
