Задача id10168

In an alternating current network with an effective voltage of 110 V, a capacitor with a capacity of 50 μF, a coil with an inductance of 200 mH and an active resistance of 4 Ohms are connected in series. Determine the amplitude of the current in the circuit if the frequency of the alternating current is 100 Hz, as well as the frequency of the alternating current at which voltage resonance occurs in this circuit.
