If an uncharged parallel-plate capacitor (capacitance C) is connected to a battery, one plate becomes negatively charged as electrons move to the plate face (areaA). In the figure below, the depth d from which the electrons come in the plate in a particular capacitor is plotted against a range of values for the potentialdifference V of the battery. The vertical scale is set by ds = 3.50 pm, and the horizontal scale is set by Vs = 40.0 V. What is the ratio C/A? (Assume that thedensity of conduction electrons is n = 8.49 1028 m-3.)
