LRC Resonance

You have an LRC series circuit: an inductor (L), resistor (R), and capacitor (C) connected in series, driven by an AC voltage source. You slowly sweep the driving frequency from very low to very high.

At resonance, when the driving frequency matches the natural frequency ω₀ = 1/√(LC), what is the total impedance of the circuit?
