About Photovoltaic Energy StorageMovement of charges onto (and away from) capacitor plates such as the inside and outside of the membrane is referred to as a current flow "through" the capacitor. In electrophysiology it is important to be aware that such currents flow ONLY when the voltage across a capacitor is changing with respect to time (the capacitor is being "charged").
