Linear Electric Current Density
lang:""
"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.
