Query: Thermodynamic optimization of an electric circuit as a non-steady energy
  converter   Electrical circuits with transient elements can be good examples of systems
where non--steady irreversible processes occur, so in the same way as a steady
state energy converter, we use the formal construction of the first order
irreversible thermodynamic (FOIT) to describe the energetics of these circuits.
In this case, we propose an isothermic model of two meshes with transient and
passive elements, besides containing two voltage sources (which can be
functions of time); this is a non--steady energy converter model. Through the
Kirchhoff equations, we can write the circuit phenomenological equations. Then,
we apply an integral transformation to linearise the dynamic equations and
rewrite them in algebraic form, but in the frequency space. However, the same
symmetry for steady states appears (cross effects). Thus, we can study the
energetic performance of this converter model by means of two parameters: the
"force ratio" and the "coupling degre". Furthermore, it is possible to obtain
the characteristic functions (dissipation function, power output, efficiency,
etc.). They allow us to establish a simple optimal operation regime of this
energy converter. As an example, we obtain the converter behavior for the
maximum efficient power regime (MPE).
