일반물리학 2 — Electromagnetic Oscillations and Alternating Current: Problem 55

55 In an oscillating \(LC\) circuit with \(C = 64.0\text{ }\mu\text{F}\), the current is given by \(i = (1.60)\sin(4100t + 0.680)\), where \(t\) is in seconds, \(i\) in amperes, and the phase constant in radians. (a) How soon after \(t = 0\) will the current reach its maximum value? What are (b) the inductance \(L\) and (c) the total energy?
