일반물리학 2 — Electromagnetic Oscillations and Alternating Current: Problem 49

49 In Fig. 31-26, \(R = 14.0\ \Omega\), \(C = 31.2\ \mu\text{F}\), and \(L = 54.0\ \text{mH}\), and the ideal battery has emf \(\mathcal{E} = 34.0\ \text{V}\). The switch is kept at \(a\) for a long time and then thrown to position \(b\). What are the (a) frequency and (b) current amplitude of the resulting oscillations?
