A charged capacitor is connected to a resistor and switch as in the figure below. The circuit has a time constant of 1.60 s. Soon after the switch is closed, the charge on the capacitor is 90.0% of its initial charge.
(a) Find the time interval required for the capacitor to reach this charge?
in seconds?
(b) If R = 260 k?, what is the value of C?
in microFarads?
