The model contains m linear resistors. Resistor no. k connects the branch voltage phasor v[k] with the corresponding branch current phasor i[k] by
R*i[k] = v[k](k=1...m).
Attention!!!
To ensure that the phasor domain-based model works in a
quasi-stationary mode, the input signal 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.
