The General Relationship between Current and Potential at an Interface

The General Relationship between Current and Potential at an Interface 

All electrode reactions manifest this type of shape. Somewhat like the situation with the examination of the proverbial elephant, the situation may seem different depending upon the point at which one touches reality. If for example, one measures an extremely low current density very near the reversible potential, it may seem that the relationship between current density and potential is a linear one, but in the large range of potentials one may obtain a logarithmic relationship between the current density and
