5 FAQs about [The initial energy storage of the energy storage element is zero]
Does an energy storage element define a dynamic process?
Of course, an energy storage element does not by itself define a dynamic process — it needs an input. That input will arise from the interaction with other system components as we will see in the following examples.
Are first-order state equations sufficient to describe energy transactions?
In the above examples, first-order state equations are sufficient to describe energetic transactions within the system; that is a consequence of the single energy-storage element. The behavior of the systems are qualitatively similar; all exhibit a non-oscillating decay to the equilibrium state Vc = 0 or q = 0.
