Nernst equation

Nernst e·qua·tion
(nārnst),the equation relating the equilibrium potential of electrodes to ion concentrations; the equation relating the electrical potential and concentration gradient of an ion across a permeable membrane at equilibrium: E = [RT / nF] [ln (C1/C 2)], where E = potential, R = absolute gas constant, T = absolute temperature, n = valence, F = the Faraday, ln = the natural logarithm, and C1 and C2 are the ion concentrations on the two sides; in nonideal solutions, concentration should be replaced by activity.

Nernst,
Walther, German physicist and Nobel laureate, 1864-1941.Nernst equation - the equation relating the electrical potential and concentration gradient of an ion across a permeable membrane at equilibrium.
Nernst potential
Nernst theory - that the passage of an electric current through tissues causes a dissociation of the ions.
