The limiting value of a
faradaic current that is approached as the rate of the charge-transfer process is increased by varying
the potential. It is independent of the
applied potential over a finite range, and is usually evaluated by subtracting the appropriate
residual current from the measured total current. A limiting current may have the character of an
adsorption,
catalytic,
diffusion, or
kinetic current, and may include a
migration current.
