Nernst equation
Etymology: Hermann W. Nernst, German physicist, 1864-1941; L, aequare, to make equal
an expression of the relationship between the electrical potential across a membrane and the ratio between the concentrations of a given species of permeant ion on either side of the membrane.

Nernst equation
gives the amplitude and sign of the electronic potential created when a semipermeable membrane separates charged ions.
