Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Contains m variable resistors (Modelica.Electrical.Analog.Basic.VariableResistor)

Attention!!!
It is recommended that none of the R_Port signals should not cross the zero value. Otherwise depending on the surrounding circuit the probability of singularities is high.
