The linear capacitor connects the branch voltage phasor v with the branch current phasor i by
i = jωC*v.The phase shift between voltage and current is -90°.
Attention!!!
To ensure that the phasor domain-based model works in a quasi-stationary
mode, the capacitance C may alter only very slowly in comparison
with both the nominal frequency f=ω/(2π) and the dominant
time constant of the phasor domain-based model.
Remark:
It is required that C ≥ 0, otherwise an assertion is raised.
