23.3: RLC Series AC Circuits
At (f_0), the effects of the inductor and capacitor cancel, so that (Z = R), and (I_{rms}) is a maximum. Resonance in AC circuits is analogous to mechanical resonance, where resonance is defined to be a forced oscillation—in this case, forced by the voltage source—at the natural frequency of the system.
