Electric Current Density
lang:""
"Electric Current Density" is a measure of the density of flow of electric charge; it is the electric current per unit area of cross section. Electric current density is a vector-valued quantity. Electric current, \(I\), through a surface \(S\) is defined as \(I = \int_S J \cdot e_n dA\), where \(e_ndA\) is the vector surface element.
