Haha... great! Thanks for your help! I had a hard time visualizing the problem on my own.

Well I am going to have to say that membrane thickness does not matter since the electric field is constant within a parallel plate capacitor since both plates run exactly parallel to each other. The voltage (perpendicular to the electric field lines) will change as you move from one plate to...

I cannot see how membrane thickness matters since it would only affect A (area), but A cancels from both sides of the equation. However, since it is included in both parts (a) and (b) I feel that thickness probably matters...

The cell membrane in a nerve cell has a thickness of 0.12 micrometers. (a) Approximating the cell membrane as a parallel plate capacitor with a surface charge density of 5.9 x 10^(-6) C/m2, find the electric field within the membrane. (b) If the thickness of the membrane were doubled, would...
