An axon is the relatively long tail-like part of a neuron, or nerve cell. The outer surface of the axon membrane (dielectric constant = 5, thickness = 1 × 10–8 m) is charged positively, and the inner portion is charged negatively. Thus, the membrane is a kind of capacitor. If the membrane acts like a parallel plate capacitor with a plate area of 5 × 10–6 m2, what is its capacitance?
