The switch in Fig. 8.73 is moved from A to B at t = 0 after being at A for a long time. This places the two capacitors in series, thus allowing equal and opposite de voltages to be trapped on the capacitors. (a) Determine vi(0), v2(0-), and vr(0-). (b) Find vi(0+), v2(0+), and vr(0+). (c) Determine the time constant of vr(t)
