Now, electrical gradient is the opposite of that. Because electrons travel this way, electrons will want to travel to the place where there is more positive charge. That means it's opposite. Now, what this number means is that when our electrical gradient and our chemical gradient equal to this number, when they're both this number, that means equilibrium will be established between the potassium ions and the same number of potassium ions will be going in as they will be coming out, right? So the rates will equal, and that's what this number means. So actually, our electrical potential should be negative of this because they're opposite of each other.
