Rich, no comment on this.
Read the quote below from my original post. You are a master at editing!
>>I didn't make myself clear enough. The maximum dissipation rating of
>>a resistor decreases as temperature increases. There is that clear enough?
So my statement still stands. If a resistor is rated at a dissipation of 10
Watts at room temperature, that dissipation rating will drop as the temperature
increases. Now if that resistor is dissipating 2 watts at room temperature and
I raise the temp 20 degrees it is still dissipating 2 watts. Of course it
follows Ohms law. But there will be a point of temperature where the resistor
will not be able to handle two watts of dissipation and will consequently fail.
End of story. No more splitting hairs.
