Solving a problem in physics, section 34, paragraph 13

13. In the AC circuit with a frequency ν = 50 Hz and the current value of the voltage U = 220 series includes a capacitor, resistor R = 50 ohms and an inductance L = 0,05 TR (see. Figure). The voltage drop U2 = 2U1. Determine: 1) the capacitance C of the capacitor 2) current value I of the current.
