Linear Electric Current Density
"Linear Electric Linear Current Density" is the electric current per unit length. Electric current, \(I\), through a curve \(C\) is defined as \(I = \int_C J _s \times e_n\), where \(e_n\) is a unit vector perpendicular to the surface and line vector element, and \(dr\) is the differential of position vector \(r\).
\(J_s = \rho_A v\), where \(\rho_A\) is surface density of electric charge and \(v\) is velocity.
