    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
