An oscillating circuit consists of an inductor TR 0.2, two parallel-connected capacitors 4.0 uF each and the ohmic resistance of 20 ohms. The initial voltage on the capacitors 20 V. Determine the period of oscillation in the circuit; logarithmic decrement; number of oscillations, after which the voltage amplitude is reduced by 10 times.

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.
