Task 31060.
An oscillating circuit consists of a coil inductance of 1.6 mH and capacitor 0.04 microfarads capacitance. Loop resistance is negligible. The maximum voltage on capacitor 200 B. Write laws change of charge on the capacitor plates and the current in the circuit with time. Determine the energy of the electric and magnetic field energy at time T / 12.
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.
