4. The electromagnetic circuit comprises a capacitor C = 1,0 nF and coil inductance L = 5,0 uH. To contour the average power supplied w = 0,50 mW to maintain it sustained oscillations at the natural frequency. The amplitude of the voltage across the capacitor Um = 3 V. Determine Q Q of the circuit, considering the damping is sufficiently small.
