For the circuit shown,
- R1 = 33 kΩ
- R2 = 82 kΩ
- R3 = 82 kΩ
- C = 220 μF

In the RC circuit, the source voltage has been at an initial voltage of Vi = -9 V for a long time. At t = 0, the source voltage abruptly jumps to Vf = 19 V.
Determine the expression for the capacitor voltage as a function of time, for t > 0.
