일반물리학 2 — Electromagnetic Oscillations and Alternating Current: Problem 54

54 A single-loop circuit consists of a $7.20\ \Omega$ resistor, a $12.0\ \text{H}$ inductor, and a $5.60\ \mu\text{F}$ capacitor. Initially the capacitor has a charge of $6.20\ \mu\text{C}$ and the current is zero. Calculate the charge on the capacitor $N$ complete cycles later for (a) $N = 5$, (b) $N = 10$, and (c) $N = 100$.
