Задача 40221.

The alternating current circuit is formed by a series-connected active resistance R=800 Ohm, inductance L=1.27 H and capacitance C=1.59 μF. A 50-cycle effective voltage U = 127 V is applied to the terminals. Find: the effective value of the current I in the circuit; phase shift between current and voltage; effective value of voltages UR, UL and UC at the terminals of each circuit element.
