We might suppose that the large inductor is close-wrapped, so that the interwinding capacitance largely cancels the inductive reactance at say 1 kHz leaving 60 ohms contribution in a series circuit of 60 ohms, 188 ohms due to the capacitor at 1 kHz, and 100 ohms, a total of 348 ohms so that the coil contributes 60/348 of 5 volts = 0.9 volts of the volts drop.


Such an inductor is not have ”pure” inductance, as BW points out. Not mentioned is most of the inductance is due to the ferromagnetic core. Does the does the µ
