Equilibrium between Ionic Concentrations Inside and Outside Cells
In a cell, if the membrane potential is at the equilibrium potential for a specific ion, there is no net tendency for that ion to move in or out of the cell

potential at which concnetration gradient still exists for an ion but there exists an exactly equal opposing electrical gradient for eg... the equilibruim potential of K+ is -90mV.. at this pint a large concnetration gradient for K still exists but no more K moves out beacuse of exactly equal opposing electrical gradient
