Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The linear resistor connects the voltage v with the
current i by i*R = v.
The resistance R is given as input signal.
The variable resistor model also has an optional conditional heat port. A linear temperature dependency of the resistance is also taken into account.
Note
A zero crossing of the R signal could cause singularities due to the actual structure of the connected network.
