The linear resistor connects the branch voltage phasor v with the branch current phasor i by
R*i = v.There is no phase shift between voltage and current.
Attention!!!
To ensure that the phasor domain-based model works in a
quasi-stationary mode, the resistance R 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 recommended that the R signal should not cross the zero
value.
