A series RLC circuit at resonance will appear to be just the resistive
portion. R in this case is the primary winding resistance - very close
to 0! Now, just ask yourself what will happen when you plug in a 100'
or so of wire to your power mains;) poof

Use a parallel combination instead.

As a general rule: series resonant circuits are low impedance,
parallel resonant circuits are high impedance.
