For the circuit shown in Figure P5.41, assume that switches S1 and S2 have been held closed for a long time prior to t = 0. S2 then opens at t = 0; however, S1 does not open until t = 96 s. Also assume
R1 = 5?, R2 = 4?, R3 = 3?, R4 = 6?, and C1 = C2 = 4F.

b. Find the time constant ? for 0 < t < 96 s.
c. Find vC for 0 < t < 96 s.
d. Find the time constant for t > 96 s.
e. Use part c to find the capacitor voltage vC at t = 96 s, and use it to find vc for t > 96s
f. Sketch vC for all time.
