Consider a capacitor C discharging through a resistor R, as shown in the figure. a. After how many time constants is the charge on the capacitor one fourth of its initial value? b. As we know, the energy stored in the capacitor decreases with time as it discharges. After how many time constants is this stored energy one fourth of its initial value? c. After how many time constants is the current in the RC circuit half its initial value? d. What is the power dissipated in the resistor during the capacitor discharge process?
