<p>This is because the entity is only in charge of creating behaviors for the simulation. After these behaviors are created, the entity has no say anymore in what happens.</p>
<p>The reason why it won't work, is that the resistor's <strong><a class="xref" href="../../../api/SpiceSharp.Components.Resistors.Temperature.html">Temperature</a></strong> behavior will derive a conductance property that is used by th
