Задача 40528.

The current strength in the oscillatory circuit, consisting of series-connected coils with an inductance of 2 H and a capacitor, varies with time according to the law I = 5 * 10 ^ -3 * sin2 * 10 ^ 3, A. Determine the capacitance of the circuit, the period of oscillations in the circuit, and the energy of the electric and magnetic fields at time t1 = T / 2. Neglect the loop resistance.

A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I try to help.
