Read the RC-transient class notes.

For the circuit shown,

• R = 4.7 kΩ
• C = 47 μF

For the RC circuit, the source voltage has been at an initial voltage of V_i = -5 V for a long time. At t = 0, the source voltage abruptly jumps to V_f = 25 V.

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

Calculate the time when the capacitor voltage will be equal to 0 V and calculate the capacitor current at that time.
