A circuit consists of a 6-pif capacitor, a 12 m-F capacitor, a 12-V battery, and a switch, connected as shown in Figure 24-14. Initially, the switch is open and the capacitors are uncharged. The switch is then closed and the capacitors charge. When the capacitors are fully charged and open-circuit terminal volt- age is restored, (a) what is the potential of each conductor in the circuit? (Choose the zero-potential reference point on the negative battery terminal.) If the potential of...
