Two capacitors of equal capacitance C are connected as shown. Initially the switch S is open, and the left capacitor is charged with charge Q, while the other capacitor is uncharged. At time t = 0 the switch is closed. (a) (7 Pts.) Find the charge on the left capacitor after charge equilibrium is reached. (b) (7 Pts.) How much energy is lost when the capacitors are connected? Now, a material with dielectric constant K is inserted to completely fill the left capacitor. The two capacitors remain connected while the material is filled. (c) (8 Pts.) What is the final charge Q′ on the left capacitor? (d) (8 Pts.) What is the total final energy stored in both capacitors?

(Figure 1) employs a convention often used in circuit diagrams. The battery (or other power supply) is not shown explicitly. It is understood that the point at the top, labeled "18.0 V ," is connected to the positive terminal of a 18.0−V battery having negligible internal resistance, and that the "ground" symbol at the bottom is connected to the negative terminal of the battery. The circuit is completed through the battery, even though it is not shown on the diagram.
