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:
“A way of certifying experience, taking photographs is also a way of refusing it—by limiting experience to a search for the photogenic, by converting experience into an image, a souvenir. Travel becomes a strategy for accumulating photographs.”
—Susan Sontag (b. 1933)
“The current of our thoughts made as sudden bends as the river, which was continually opening new prospects to the east or south, but we are aware that rivers flow most rapidly and shallowest at these points.”
—Henry David Thoreau (1817–1862)
