modelResistor
Single-phase linear resistor
Extends from Interfaces.OnePort (Two pins, current through), Modelica.Electrical.Analog.Interfaces.ConditionalHeatPort (Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network).
Information
The linear resistor connects the complex voltage v with the complex
current i by i*R = v.
The resistance R is allowed to be positive, zero, or negative.
The resistor model also has an optional conditional heat port. A linear temperature dependency of the resistance is also taken into account.
