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)
“You will belong to that minority which, according to current Washington doctrine, must be protected in its affluence lest its energy and initiative be impaired. Your position will be in contrast to that of the poor, to whom money, especially if it is from public sources, is held to be deeply damaging.”
—John Kenneth Galbraith (b. 1908)
