QUE SIGNIFIE CURRENT DENSITY EN ANGLAIS
La densité actuelle
Dans l'électromagnétisme et les domaines connexes en physique à l'état solide, la physique de la matière condensée, etc. la densité du courant est le courant électrique par unité de surface de la section transversale. Il est défini comme un vecteur dont la grandeur est le courant électrique par section transversale à un point donné dans l'espace. Dans les unités SI, la densité du courant électrique est mesurée en ampères par mètre carré.
définition de current density dans le dictionnaire anglais
La définition de la densité de courant dans le dictionnaire est le rapport entre le courant électrique circulant en un point particulier dans un conducteur et la section transversale du conducteur prise perpendiculairement à l'écoulement du courant à ce point. Il est mesuré en ampères par mètre carré J.
