The departure of an electrode potential from its equilibrium value required to sustain a specified current under kinetic and transport losses.

This is an authored directed relation from the source endpoint to the target endpoint.
Under its stated assumptions, the equation relates activation overpotential to the net current through anodic and cathodic partial-current terms; measured overpotential can also include transport and resistive contributions outside that relation.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

An operating electrode has an overpotential relative to a defined equilibrium potential; charge transfer, mass transport, resistance, bubbles, area, and reference placement can all contribute.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
