      Second order circuits are not necessarily simple series or parallel RLC circuits. Any two non-combinable storage elements (e.g., an L and a C, two L’s, or two C’s) yields a second order circuit and can be solved as before, except that the and are different from the simple series and parallel RLC cases. An example follows.
