first, post a specific circuit or layout ....

Also state the frequency in question as well as the circuit "Q", as well info requested by IrishBoy123.

an LC circuit is just an inductance connected to a capacitor in series, and if we are assuming the max current, we know the freq should be : $\omega = \frac{1}{\sqrt{LC}}$ but i guess we still need Q...

For their to be voltage and current, there needs to be an excitation source. Now when a source is considered, you need to know if the the source is in series with the LC or parallel with the LC|dw:1433172751757:dw|

I agree with you @radar , but don't forget the case of a charged capacitor and an inductance connected in series, without any source, an LC series circuit (one without any resistance) would "oscilate", actually the charge or energy would oscillate from L to C and back. I guess we need to specify which case is the question about!

Medals 0 @Greg_D True, we would have to consider the "charged" capacitor or the "charged" inductor (one having a magnetic field surrounding it) as either a source or maybe even connected to a source. The "resistance" you mentioned would play a key role as it established the "Q" of the circuit. I imagine that the configuration would play a role also. The problem is asking for a procedure on "how to find max I & E" . I would need some specifics as mentioned previously.

i agree again, we need to know which of those circuits is the one for this question
