Information

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

The linear resistors connect the complex voltages v with the complex currents i by i*R = v, using m single phase variable Resistors. The resistances R are given as m input signals.

The resistor model also has m optional conditional heat ports. A linear temperature dependency of the resistances is also taken into account.
