일반물리학 2 — Electromagnetic Oscillations and Alternating Current: Problem 56

56 An oscillating LC circuit has a current amplitude of 7.50 mA, a potential amplitude of 280 mV, and a capacitance of 220 nF. What are (a) the period of oscillation, (b) the maximum energy stored in the capacitor, (c) the maximum energy stored in the inductor, (d) the maximum rate at which the current changes, and (e) the maximum rate at which the inductor gains energy?
