Problem 4.104

An oscillating circuit consists of a capacitor with capacitance \(C=4.0 \mu \mathrm{F}\) and a coil with inductance \(L=2.0 \mathrm{mH}\) and active resistance \(R=10 \Omega\). Find the ratio of the energy of the coil's magnetic field to that of the capacitor's electric field at the moment when the current has the maximum value.
