Created by StemPy LabA coil of resistance and reactance is joined to a V (rms) source. What average power does it take?

← At its resonant frequency, a series LCR circuit has an inductive reactance equal to its resistance. The frequency of the source is now doubled. By what angle does the current lag the voltage?In a series LCR circuit the resistance equals the inductive reactance, and the capacitive reactance is half of that. What is the power factor? →
