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 dc voltages to be trapped on the capacitors,(a) Determine υ1 (0−), υ2(0−), and υR (0−). (b) Find υ1 (0+), υ2(0 +), and υR(0+). (c) Determine the time constant of υR(t). (d) Find υR(t), t > 0.(e) Find i(t). (f) Find υ1 (t) and υ2(t) from i(t) and the initial values. (g) Show that the stored energy at t = ∞ plus the total energy dissipated in the 20 kΩ resistor is equal to the energy stored in the capacitors at t = 0.
