A 19.8 kΩ resistor and a capacitor are connected in series and then a 12.0 V potential difference is suddenly applied across them. The potential dissimilarity across the capacitor raises to 8.83 Vin 1.92 µs. (a) Compute the time constant of the circuit (inμs). (b) Find the capacitance of the capacitor in nanofarads.
