Like series circuits, parallel RLC circuits (containing inductors and capacitors) are second-order with a resonant frequency. Both are affected by frequency changes. However in parallel resonance, it is the current through the circuit that reaches a minimum at resonance, not the impedance. The focus here is, how currents in each …
