why at the resonance frequency the impedance of the circuit reduces to R, i.e. why the LC part of the circuit appears to be invisible? (LCR circuit in series).

how accurately can resonant RLC circuit discriminate between different driving frequencies?
 

the impedance of L is 2*pi*f*L
that of capacitor is 1/(2*pi*f*C)

the impedances are frequency dependent.

these impedances are equal at resonance.

the voltage across them are 180 degrees apart at resonance.
they cancel out leaving only R.

the accuracy is dependent on Q
