## current density

https://doi.org/10.1351/goldbook.C01452
The current density $$j_{\mathbf{B}}$$ of a species B in a given point of the solution is obtained by multiplying the flux density of that species at the given point by the @[email protected] $$F$$ and by the @[email protected] $$z_{\text{B}}$$ of the species: $j_{\mathbf{B}} = z_{\text{B}}\ F\ N_{\mathbf{B}}$ where $$j_{\mathbf{B}}$$ is a vector which indicates the direction in which the charges transported by the species B flow and which gives the number of these charges going through a plane oriented perpendicular to the vector, divided by time and by area, and $$N_{\mathbf{B}}$$ is the flux density of a minor @[email protected] of the solution with respect to a fixed frame of reference.
