ток проводимости
Явление направленного движения свободных носителей электрического заряда в веществе или в пустоте, количественно характеризуемое скалярной величиной, равной производной по времени от электрического заряда, переносимого свободными носителями заряда сквозь рассматриваемую поверхность.
[ ГОСТ Р 52002-2003]EN
(electric) current
(conduction) current
scalar quantity equal to the flux of the electric current density J through a given directed surface S:
where endA is the vector surface element
NOTE 1 – The electric current through a surface is equal to the limit of the quotient of the electric charge transferred through that surface during a time interval by the duration of this interval when this duration tends to zero.
NOTE 2 – For charge carriers confined to a surface, the electric current is defined through a curve of this surface (see the note to term “lineic electric current”).

courant (électrique), m
courant (de conduction), m
grandeur scalaire égale au flux de la densité de courant électrique J à travers une surface orientée donnée S:
où endA est l'élément vectoriel de surface
NOTE 1 – Le courant électrique à travers une surface est égal à la limite du quotient de la charge électrique traversant cette surface pendant un intervalle de temps par la durée de cet intervalle lorsque cette durée tend vers zéro.
NOTE 2 – Pour des porteurs de charge confinés sur une surface, le courant électrique est défini à travers une courbe de cette surface (voir la note au terme "densité linéique de courant").
