And this moment in time is known as the equilibrium point. So when these cations reach their equilibrium points, there will still be an unequal distribution of these molecules, these ions. And at that moment in time, we can calculate exactly what that voltage potential difference is. What that voltage difference is between the two sides of the membrane. And if we carry the same exact procedure as with the other ions, and then we take the average of those values, that will give us the resting membrane potential, So the electric potential difference across the membrane at the equilibrium point is what we call the resting membrane potential. So the resting potential is a result of the existence of the unequal distribution of these charged ions across that cell membrane.
