Equilibrium potential for one ion is determined by the Nernst equation for that ion. For example, i o K K K nF RT E ] [ ] [ ln + + = i o Na Na Na nF RT E ] [ ] [ ln + + = Resting membrane potential is determined by the membrane permeabilities and equilibrium potentials of several ions. Goldman, Hodgkin and Katz assumed a constant electric field across the membrane to derive the steady state membrane potential:
