A 13.4 kΩ resistor and a capacitor are linked in series and then a 12.0 V potential dissimilarity is suddenly applied across them. The potential dissimilarity across the capacitor raises to 4.91 V in 1.56µs. (a) Compute the time constant of the circuit (inμs). (b) Discover the capacitance of the capacitor in nanofarads.
