At the resonant frequency of a series RLC band-pass filter, the impedance of the filter should be minimum. This is because the reactive elements in the circuit cancel out their effects, leaving only the resistive element which has a minimum impedance at resonance. Current flow through the load and the output voltage across the load are at their maximum at resonance.
