If the charging current is negligible, in the case of a single electrode reaction, the electrode current density (c.d.) of the electric current flowing through the electrode is related to the flux density of a species **B** by the equation: \[j = n\ \nu _{\text{B}}^{-1}\ F\ \left(N_{\text{B}}\right)_{e}\] where (NB)e is the normal component of the vector NB at the electrode-solution interface, n is the charge number of the electrode reaction and νB is the stoichiometric number of species **B**. The ratio n/νB is to be taken as positive if the species **B** is consumed in a cathodic reaction or produced in an anodic reaction. Otherwise it is to be taken as negative. With the convention that the normal distance vector points into the electrolytic solution, a cathodic current is then negative, an anodic current positive.*Source: *
