The cell membrane in a nerve cell has a thickness of 0.12 mm. (a) Approximating the cell
Question:
The cell membrane in a nerve cell has a thickness of 0.12 mm.
(a) Approximating the cell membrane as a parallel-plate capacitor with a surface charge density of 5.9 × 10-6 C/m2, find the electric field within the membrane.
(b) If the thickness of the membrane were doubled, would your answer to part (a) increase, decrease, or stay the same? Explain.
