Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This models a potentiometer where the sliding contact is placed between pin_n (r = 0) and pin_p (r = 1), dependent on either the parameter rConstant or the signal input r.
The total resistance R is temperature dependent.
