Read the RC-transient class notes.

For the circuit shown,

• R₁ = 680 Ω
• R₂ = 470 Ω
• R₃ = 270 Ω
• C = 4.7 μF

In the RC circuit, the source voltage has been at an initial voltage of V_i = -9 V for a long time. At t = 0, the source voltage abruptly jumps to V_f = 30 V.

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