    Find the energy stored in each capacitor and inductor, under steady-state conditions, in the circuit. (picture attached)

    I know the energy for capacitors is:
    W=(1/2)CV^2
    the energy for inductors is:
    W=(1/2)Li^2

    I am not for sure what to use for V and i. I was going to use nodal analysis to find the values for i and V but do the inductors and conductors affect the analysis?

    Yes, the inductor will affect the analysis.

    I think you should go with your intentions and complete the nodal analysis. Once you have determined all of the steady-state dc voltages across all of the capacitors and the inductor then you will be able to apply the formulas for energy you have included in your posting.

    Once you have completed your analysis, post it here for review by our members.

    "...dc voltages across all of the capacitors and the current through the inductor..."
