A model of a red blood cell portrays the cell as a spherical capacitor, a positively charged liquid sphere of surface area A separated from the surrounding negatively charged fluid by a membrane of thickness t. Tiny electrodes introduced into the interior of the cell show a potential difference of 100 mV across the membrane. The membrane's thickness is estimated to be 95 nm and has a dielectric constant of 5.00 (a) If an average red blood cell has a...

The fluids inside and outside a cell are good conductors separated by the cell wall, which is a dielectric. Thus the cell has capacitance; charge may be stored on its inner and outer surfaces (see the figure below). It is a good approximation to treat the thin charged layer as a parallel-plate capacitor. Typically the wall is 9.50 x 10-9 m thick and has a dielectric constant of 5.00. (everybody's responses to this question before were incorrect so I need...
