Consider the circuit shown in the gure. A short time after closing the switch, the charge on the capacitor is 95.0% of its initial charge. Assume the circuit has a time constant of 21.2 s. (a) Calculate the time interval required (in s) for the capacitor to reach this charge. I I S (b) If R = 200 kn, what is the value of C (in HF)? i. W
