Fig. 2. The magnitude of the impedances for the capacitor, inductor and parallel combination as functions of frequency of the source. A sharp peak occurs at the resonance frequency for the impedance of the parallel combination. Since the total circuit impedance has a maximum value at the resonance, the current from the source must be a minimum at the resonance frequency (figure 3).
