The limiting current, in electrochemistry, is the limiting value of a faradaic current that is approached as the rate of charge-transfer to an electrode is increased . The limiting current can be approached, for example, by increasing the electric potential or decreasing the rate of mass transfer to the electrode. 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 can have the character of an adsorption, catalytic, diffusion, or kinetic current, and may include a migration current.

Famous quotes containing the words limiting and/or current:
“There could be no fairer destiny for any physical theory than that it should point the way to a more comprehensive theory in which it lives on as a limiting case.”
—Albert Einstein (1879–1955)
“Phlebas the Phoenician, a fortnight dead,
Forgot the cry of gulls, and the deep sea swell
And the profit and loss.
A current under sea
Picked his bones in whispers. As he rose and fell
He passed the stages of his age and youth
Entering the whirlpool.”
—T.S. (Thomas Stearns)
