C = 680μF
L = 10μH
R = 0.04 Ω
Switch Q and Diode D are ideal.
Capacitor C is initially charged to VC0 = 1 KV
At t = 0, ideal switch Q closes.
Calculate the following:
1. The inductor current iL(t), for t ≥ 0, and sketch it.
2. The time when the ideal diode D turns on.
3. The peak inductor current IL,MAX.
4. The energy dissipated in R.
