In Figure P28.71, suppose the switch has been closed for a time sufficiently long for the capacitor to become fully charged. Find
(a) The steady-state current in each resistor and
(b) The charge Q on the capacitor.
(c) The switch is now opened at t = 0. Write an equation for the current through R2 as a function of time and
(d) Find the time interval required for the charge on the capacitor to fall to one-fifth its initial value.
