Задача 30888.

An oscillating circuit consists of a coil inductance of 0.4 TR and capacitor 2.5 uF. The total energy of the circuit 2 * 10 ^ -6 J. Write the law of change of current and potential difference across the capacitor plates over time, assuming that the initial time the maximum charge on the capacitor. Loop resistance neglected.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
