The circuits (a) and (b) below caontain capacitors that can be discharged. Answer the following questions for both capacitors.
(a) When the capacitor is fully charged, the battery is removed from the circuit. What is the charge on the capacitor as a function of time as the capacitor is discharging? Assume that the battery is removed at time t = 0.
(b) What is the current through the resistor as a function of time as the capacitor is discharging?
(c) At what time when the capacitor is discharging will the current through the resistor be 1 μA?
