Energy stored in a capacitor

  1. Jan 8, 2016 #1
    1. The problem statement, all variables and given/known data

    How to find the energy stored in the capacitor in steady state in this circuit.

    2. Relevant equations


    3. The attempt at a solution
    I found out the charge on the capacitor in steady state using loop law and did energy stored = (Q^2)/2C. but its coming out to be incorrect.

    What is the expression for energy in terms of C and V? In steady state, voltage and capacitance will be known to you.

    But we also know the charge on the capacitor in steady state. Don't we?
    Then why is it coming incorrect using this method.

    You need to show your work. We can't say much about what you did wrong if we don't know what you did.
