A pretty difficult problem about oscillatory circuit

  1. Dec 5, 2007 #1
    An oscillatory circuit

    1. The problem statement, all variables and given/known data
    So, there are parameters of a circuit. Also we got an answer. Just look at image below in the attachments.


    2. Relevant equations
    This problem uses simple differential equations. All I could write down here is on the wikipedia page: http://en.wikipedia.org/wiki/LC_circuit


    3. The attempt at a solution
    After some pondering, I've got something about that.
    [tex]\epsilon=L_{1}\frac{dI}{dt}[/tex]
    [tex]\epsilon_{c}=-L_{2}\frac{dI}{dt}[/tex]
    [tex]U=I*R[/tex]
    [tex]U\epsilon_{c}=\frac{q}{C}[/tex]
    So that:
    [tex]IR+\frac{q}{c}=\frac{dI}{dt}(L_{1}-L_{2})[/tex]
