Weblayer produces an average electric field. On account of the complete and exact shielding of the electrode charge, as illustrated by condition (8), this mean field will be nonzero only within the Gouy layer. By integration, the field defines an average potential if;(r) at a point r in the double layer relative to the bulk liquid.
