Read the RC-transient class notes.
For the circuit shown,
- R = 27 Ω
- C = 220 nF
- IS = 1.1 A
In the RC circuit, the switch has been open for a long time and closes at t = 0. Prior to the switch closing, the capacitor was charged to a voltage of Vi = -7 V.
Determine the expression for the capacitor voltage as a function of time, for t > 0.
