integral capacitance of an electrode

Integral capacitance (per unit area of electrode) is given by

$Math - e$

where $Math - text$ is the electric charge (per unit area of electrode), $Math - text$ is the potential of the electrode with respect to a reference electrode, and $Math - text$ is the potential at the point of zero charge.
