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. Assuming that an axon can be treated like a parallel plate capacitor with a plate area of 4.7 10-6 m2, what is its capacitance?
I used the formula C = (KE0 A )/ d
and assigned the following:
KE0 = 5
A = 4.7 x 10^-6 m2
d = 1 x 10^-8 m
and came up with:
C= 2350.
this isn't correct though.
What am I doing wrong?
