Step 1
Step 1: Calculate the strength of the electric field within the cell membrane using the formula E = ΔV / d, where E is the electric field strength, ΔV is the potential difference (90 mV), and d is the thickness of the cell membrane (8 nm). Show more…

The electric field within a cell membrane is approximately $8.6 \mathrm{MV} / \mathrm{m}$ and is essentially uniform. If the membrane is $18 \mathrm{~nm}$ thick, what's the potential difference across the membrane?
A 9.0-nm-thick cell membrane undergoes an action potential that follows the curve in the table on page 748 . What is the strength of the electric field inside the membrane just before the action potential and at the peak of the depolarization?
(I) What is the magnitude of the electric field across an axon membrane 1.0 $\times$ 10$^{-8}$ thick if the resting potential is -70mV?
