In an ideal resonant circuit inductance is L = 2 * 10 ^ -7 Mr occur undamped electromagnetic oscillations. The amplitude of the charge on the capacitor plates and the current in the circuit are respectively qm = 2 × 10 -8 Kd = 1 and Im A. Determine oscillation period T and the time when Wel electrostatic field energy in the capacitor is n = 0.75 of the total energy W circuit: Wel / W = n = 0.75.
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
If you have any questions to address, please. I´ll try to help.
