Transient dynamic DC electrical systems are often characterized by response time, amount of damping, and dynamic behavior of outputs in terms of input functions. This investigation correlates some of these standard responses in terms of nonequilibrium entropy generation rates to illustrate the concept of thermodynamic equivalence of metastable DC electrical systems. A resistor, inductor, capacitor (R, L, Ca, respectively) series circuit is subjected to a direct current (DC) step load change in voltage and the response is characterized using standard methodologies and compared/contrasted to the thermodynamic approach in which the metric is entropy generation rate. It is determined that metastable equilibrium is equivalent to the rate of change of entropy generation rate with respect to temporal rate of change in voltage of the dissipative resistor component. Using combined 1 st and 2 nd Laws of Thermodynamics, the total entropy generated is directly related to the thermal waste energy of the circuit.
