CE ÎNSEAMNĂ CURRENT DENSITY ÎN ENGLEZĂ?
Densitatea curentă
În electromagnetism și în câmpurile conexe din fizica solidă, fizica materiei condensate etc. densitatea curentului este curentul electric pe unitatea de suprafață a secțiunii transversale. Este definit ca un vector al cărui magnitudine este curentul electric pe suprafața secțiunii transversale într-un punct dat în spațiu. În unitățile SI, densitatea curentului electric este măsurată în amperi pe metru pătrat.
Definiția current density în dicționarul Engleză
Definiția densității curente în dicționar este raportul dintre curentul electric care curge într-un anumit punct al unui conductor și cel al secțiunii transversale a conductorului, perpendicular pe fluxul curent din acel punct. Se măsoară în amperi pe metru pătrat J.
