  • Deviation of the potential of an electrode from its equilibrium value required to cause a given current to flow through the electrode. [en]
  • Difference between the electrode potential with current flow, and the electrode potential without current flow, i.e. the equilibrium potential. [en]
  • Overpotential is positive for oxidation reactions and negative for reduction reactions. [en]
  • Overpotential is the extra potential, in relation to the equilibrium value, required to cause a given electric current to flow through the electrode. [en]
