1. The problem statement, all variables and given/known data

A 5 Micro-F Capacitor, a 65mH Inductor, and a 10 Ohm resistor are connected in series
Find the resonant frequency of this circuit.
Determine the peak current at resonance, if the peak voltage is 100V

2. Relevant equations

Fr = (1/2Pi) Square Root(1/LC)
I don't know the equation for Peak Current ... HELP!

3. The attempt at a solution

Resonant Frequency = 883 Hertz
Maximum Current = 10 Amps

You should have calculated the peak current by doing:
$$I_{peak} = \frac{V_{peak}}{Z_{total}}$$
Where Z_total is the total impedance of the circuit.
