Description

This is a model for an electrical resistor where the generated heat is dissipated to the environment via connector heatPort (bottom) and where the resistance R is temperature dependent according to the following equation:

HeatingResistor_equation1

alpha is the temperature coefficient of resistance, which is often abbreviated as TCR. In resistor catalogues, it is usually defined as X [ppm/K] (parts per million, similarly to per centage) meaning X*1.e-6 [1/K]. Resistors are available for 1 .. 7000 [ppm/K], i.e., alpha = 1e-6 .. 7e-3 [1/K].

Parameters
