A drawing I made of a basic RC circuit superimposed on a membrane bilayer. Made in CorelDraw!

Caption (from action potential):

Part A: A basic RC circuit, superimposed on an image of a membrane bilayer to show the relationship between the two. Part B: A more elaborate RC circuit, superimposed on an image of a membrane bilayer. This RC circuit represents the electrical characteristics of a minimal patch of membrane containing at least one Na and two K channels. Elements shown are the transmembrane voltages produced by concentration gradients in potassium (green) and sodium (blue), The voltage-dependent ion channels that cross the membrane (variable resistors;K=green, Na=blue), the non-voltage-dependent K channel (black), and the membrane capacitance.
