The cell membrane of neuron maintains intracellular conditions that differ from those of the extracellular environment. Such difference in intra- and extracellular conditions are critical to the function of the nerve cell as the nerve cell membrane resembles a charged capacitor. Assuming the electric field (E) across a parallel-plate capacitor is uniform and if membrane thickness is 7nm and potential difference across the membrane is – 60 mV, calculate E of the membrane.
