The circuit consists of a series-connected capacitor with electrical capacity C = 2 μF, a coil with inductance L = 0.51 H and electrical resistance E = 100 Ohm. Determine the effective value of the current in the circuit if an alternating voltage U = 220 V (rms value) with a frequency v = 50 Hz is supplied to it. Determine the effective voltage values on the individual elements of the circuit, the current in the circuit and cos f, where f is the phase shift between the fluctuations of current and voltage. Calculate at what electrical capacitance of the capacitor voltage resonance would occur. Determine the characteristic impedance and quality factor.
