Read the RC-transient class notes.
For the circuit shown,
- R = 5.6 kΩ
- C = 1.5 nF
- VS = 3 V
For 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 = -13 V.
Determine the expression for the capacitor voltage as a function of time, for t > 0.
Calculate the capacitor voltage and capacitor current at t = 4.2 μs.
