This model shows how to use a two port resistance-capacitance model.
The example also shows a comparison between the dynamic and steady state version model
that can be selected by changing the boolean flag use_C.
In this example the RC connects an ideal constant voltage source with a short circuit. The steady state current value passing through the RC model depends just on the value of R.
The RC model implement a T-model to represent the electric connection between the two connectors (see Buildings.Electrical.DC.Lines.TwoPortRCLine for more details).
The capacitance C see an equivalent Thevenin's resistance that is equal to REQ = 0.5 R and thus the time constant associated to the capacitance is
τ = REQ C = 0.5 R C = 2 seconds,
thus the duration of transient period is about 10 seconds.
