Electric Field As Derivative of Potential Video Lessons

Concept

# Problem: A 8.0 nm thick cell membrane undergoes an action potential that follows the curve in the figure.What is the strength of the electric field inside the membrane at the peak of the depolarization?

###### FREE Expert Solution

Electric field:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{-}}\frac{\mathbf{∆}\mathbf{V}}{\mathbf{∆}\mathbf{x}}}$

At the peak of depolarizatin, ΔV = 40mV(10-3V/1mV) = 40 × 10-3 V
