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 IR2 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.
