Read the RC-transient class notes.

For the circuit shown,

• R₁ = 1.8 kΩ
• R₂ = 2.2 kΩ
• R₃ = 3.3 kΩ
• C = 2.2 μF

In the RC circuit, the source current has been at an initial of I_i = -7 mA for a long time. At t = 0, the source current abruptly jumps to I_f = 12 mA.

Determine the expression for the capacitor voltage as a function of time, for t > 0.
