Solved: a) Suppose the circuit in Fig. 8.21 has a 5 nH inductor and a 2 pF capacitor

Chapter 8, Problem 8.66

(choose chapter or problem)

a) Suppose the circuit in Fig. 8.21 has a 5 nH inductor and a 2 pF capacitor. Calculate the frequency, in GHz, of the sinusoidal output for \(t \geq 0\).

b) The dc voltage source and series-connected resistor in Fig. 8.21 are used to establish the initial energy in the inductor. If V = 10 V and \(R=25 \Omega\), calculate the initial energy stored in the inductor.

c) What is the total energy stored in the LC circuit for any time \(t \geq 0 ?\)?
