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 (area A ). In Fig. 25-26, the depth d from which the electrons come in the plate in a particular capacitor is plotted against a range of values for the potential difference V of the battery. The density of conduction electrons in the cooper plates is 8.49 × 10 28 electrons/m 3 . The vertical scale is set by d s = 1.00 pm, and the horizontal scale is set by V s = 20.0 V. What is the ratio C / A ? Figure 25-26 Problem 7.
