Resonance Curve - Do I have enough info?

[phyzmatix]

Homework Statement

For a sinusoidally driven RLC circuit.

Draw accurate resonance curves for C = 0.01uF, L = 0.01mH and
i) R = 20 ohm
ii) R = 200 ohm

2. The attempt at a solution

Believe it or not, I do not have a single example of resonance curves in any of my textbooks. However, from my internet searches, I believe the resonance curves are supposed to look something like the one here:

http://hyperphysics.phy-astr.gsu.edu/HBASE/electric/imgele/qresi.gif"

I know that at resonance,

i_0=\frac{V_0}{R}

also

\omega_0 = \frac{1}{\sqrt{LC}}

and that

i=i_0\cos(\omega t + \phi)

But how do I bring this all together into something coherent? Am I not supposed to know what V0 is?

Thanks!

If you're not given Vo, you could plot the ratio I_rms/Vo_rms instead of just I_rms.

This will involve calculating the complex impedance Z for the circuit, which can be used to get I_rms/Vo_rms.
