An oscillating LC circuit consisting of a 7.5 nF capacitor and a 4.4 mH coil has a maximum volatage of 2.0 V. What is the maximum current through the circuit?

I got 1.5x10^-8 C for the max. charge.

$$\frac{1}{2}L I_m^2=\frac{1}{2}CU_m^2$$

Got it. Forgot about the ability to set those equal to each other in oscillation.

Thanks!
