Definition

scalar quantity equal to the quotient of the net quasi-infinitesimal (see IEC 60050-121,locality:item="121-11-06") electric charge $d Q$ (electric charge) transferred through a surface during a quasi-infinitesimal time interval and the duration $d t$ of that interval:

I = \frac{d Q}{d t}

grandeur scalaire égale au quotient de la charge électrique $d Q$ (electric charge) quasi-infinitésimale nette (voir l'IEC 60050-121,droploc%locality:item="121-11-06") traversant une surface pendant un intervalle de temps quasi-infinitésimal par la durée $d t$ de cet intervalle;

I = \frac{d Q}{d t}

Notes

Electric current is one of the base quantities in the International System of Quantities, ISQ, on which the International System of Units, SI, is based.

Electric current $I$ through a surface $S$ can also be written as

I = \int_{S}^{} J \cdot e_{n} d A

where $J$ is the electric current density (electric current density) and where $e_{n} d A$ is the vector surface element.

Electric current produces a magnetic field.

For related definitions, see electric current density and IEC 60050-121,locality:item="121-11-13".

Le courant électrique est l'une des grandeurs de base dans le Système international de grandeurs, ISQ, sur lequel repose le Système international d'unités, SI.

Le courant électrique $I$ traversant une surface $S$ peut également s'écrire sous la forme

I = \int_{S}^{} J \cdot e_{n} d A

où $J$ est la densité de courant électrique (electric current density) et où $e_{n} d A$ l'élément vectoriel de surface.

Le courant électrique produit un champ magnétique.
