Figure 25-41 shows a circuit section of four air filled capacitors that is connected to a larger circuit. The graph below the section shows the electrin potential V(x) as a function of position x along the lower part of the section, through capacitor 4. Similarly the graph above the section shows the electric potential V(x) as a function of position x along the upper part of the section, through capacitors 1,2 and 3 capacitors 3 has a capacitance of 1.60 mu F What are the capacitances of (a) capacitor 1 and (b) capacitor 2?

In Fig. 25-7a switch S is closed to connect the uncharged capacitor of capacitance C = 0.25 mu F to the battery of potential difference V=12V. The lower capacitor plate has thickness L=0.50 cm and face area A= 2.0 times 10^-4 m^2 and it consists of copper in which the density of conduction electrons is n=8.49 times10^25 electrons/ m^3 . From what depth d within the plate (Fig.25-7b) must electrons move to the plate face as the capacitor becomes charged?
