Solved: In the circuit shown in Fig. 8.1, a 20 mH inductor is shunted by a 500 nF
Chapter 8, Problem 8.8(choose chapter or problem)
In the circuit shown in Fig. 8.1, a 20 mH inductor is shunted by a 500 nF capacitor, the resistor R is adjusted for critical damping, and \(I_{0}=120 \mathrm{~mA}\).
a) Calculate the numerical value of R.
b) Calculate v(t) for \(t \geq 0\).
c) Find v(t) when \(i_{C}(t)=0\).
d) What percentage of the initially stored energy remains stored in the circuit at the instant \(i_{C}(t)\) is 0?
