When an ion channel opens, we can use the Nernst equation to calculate membrane potential. Why? This is the equation used to measure ion flow rates. The other ions have no permeability. The permeability of that ion is much, much higher than it is for other ions. This equation is always used to measure membrane potential. At that time, there is a concentration difference for ions between the inside and outside
