Task 40325.
The capacitance C, the resistance R, and the inductor L are connected in series to the alternating current circuit. The amplitude of the alternating voltage is Um = 220 V. Find the amplitude of the voltage drop across the capacitor UCm, the resistance URm, and the inductance ULm, if it is known that the external voltage is ahead of the current in phase by 30 °, and ULm = 4 * UCm.
A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I try to help.
