How is a series resonance 30,000 ohms?   

I’m kind of dumb, but I thought at series resonance , reactive components cancel and all that is left is the tiny ohmic resistance of the wire. 

What am I missing?

Very high, about 30 K. It actually helps us.

probably does matter.   At the self resonant point the series impeane will be very low....

does it matter that most 27uH inductors seem to have a self resonant frequency below 28MHz?
