Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The linear resistor connects the branch voltage v with the branch current i by
i*R = v
The Resistance R is given as input signal.
Attention!!!
It is recommended that the R signal should not cross the zero value. Otherwise depending on the surrounding circuit the probability of singularities is high.
