In fact, an action potential is a moving electric current. So from this same equation, we can see that an axon with a larger diameter will propagate that action potential much quicker because the larger diameter means we have a larger area and a thicker area. And so that means a lower resistance. At the same exact time. If we decrease the length of that axon, we decrease the L. And so we decrease our resistance and we increase the speed of the movement of that action potential inside our axon. And this is summarized in these two diagrams.
