  1. Nov 15, 2011 #1
    1. The problem statement, all variables and given/known data



    Find the conservation of electrical energy in the LCR


    2. Relevant equations
    LdQ^2/dt + Q/C = 0

    LdQ^2/dt + RdQ/dt + Q/C = 0


    3. The attempt at a solution

    LdQ^2/dt + Q/C = RdQ/dt

    Which LCR? Theres no diagram!

    Also, derivate notation involves the same power on top as the bottom, i.e d^2Q/dt^2, so can you double check your listed relevant equations.
