Part II - Solve the following problems Q1. (8 points) In the circuit shown, the capacitor is initially 69 (2 points each = 20 points) uncharged and the switch S is closed to point a until the capacitor is fully charged. The switch is then closed to point S b in order to discharge the capacitor. (2 points each) 12 V- a. Find the charge on capacitor when it is fully charged? 2180 6 HF 260 b. Calculate the discharging time constant (T) for the capacitor? c. What is the current at the instant of closing switch S to b? d. What is the current after 72 us of closing switch S to b
