Homework Help: RLC circuit with more the 2 storage elements

  1. Feb 19, 2009 #1
    1. The problem statement, all variables and given/known data
    There is no real problem, so I'll just make up a arbitrary one. A series RLC circuit with a voltage source x(t), but say there is a resistor in parallel with the capacitor, followed by an inductor in parallel with that resistor. Just assume all the values of the inductors, resistors, and capacitor are 1 to make it easy.

    2. Relevant equations
    How would you derive a differential equation for an RLC circuit that contains more than 2 storage elements? I know the equation should be a 3rd order DE since it'll contain 3 storage elements, but I don't really know how to go about finding it. I can do series and parallel RLC's fine, but when it involves an extra storage element i get thrown off.
