THE NERNST EQUATION RELATES THE MEMBRANE POTENTIAL TO THE DISTRIBUTION OF AN ION AT EQUILIBRIUM

THE NERNST EQUATION RELATES THE MEMBRANE POTENTIAL TO THE DISTRIBUTION OF AN ION AT EQUILIBRIUM. ? E j = 59mV log C j o / C j i (6.11) 1. A tenfold difference in concentration (outside > inside) corresponds to a Nernst potential of +59mV (C o /C i = 10/1; log 10 = 1).
