Review A typical cell has a membrane potential of -70 mV, meaning that the potential inside the cell is 70 mV less than the potential outside due to a layer of negative charge on the inner surface of the cell wall and a layer of positive charge on the outer surface. This effectively makes the cell wall a charged capacitor. Because a cell's diameter is much larger than the wall thickness, it is reasonable to ignore Part A How much energy stored in the electric field of a 50-um-diameter cell with a 7.0-nm-thick cell wall whose dielectric constant is 9.0? the curvature of the cell and think of it as a parallel- plate capacitor. Express your answer with the appropriate units.
