That's a good homework question.

You will need to show your attempt first. Then, members will help you by pointing out any errors in your attempt, and give you some guidance in putting you on the right track. This forum does not simply do your homework for you.

v/s=i(s)(R+SL+1/SL)
I(S)=V/(SR+S^2+1/C)
I(S)=V/L *(1/S^2+R/L*S+1/LC)
SO WHAT IS THE I(T)

I'm actually interested in knowing the answer myself, ha, so you had better figure it out!

Anyways, as a hint, I'm pretty sure the output over time will be a sine wave, but other than that I can't really tell
