Process 1 : In the circuit the switch S is closed at and the capacitor is fully charged to voltage v_(0) (i.e., charging continues for time T >> RC). In the process some dissipation (E_(D)) occurs across the resistance R. The amount of energy finally stored in the fully charged capacitor is E_(C) . Process 2 : In a different process the voltage is first set to (v_(0))/(3) maintained for a charging time T >> RC. Then the voltage is raised to (2V_(0))/(3) without discharging the capacitor and again maintained for a time T >> RC. The process is repeated one more time by raising the voltage to v_(0) and the capacitor is charged to the same final voltage v_(0) as in process 1. These two processes are depicted in Figure 2.
