Once a resistor becomes faulty, perhaps through excessive current and heating, does it generally open, or does it sometimes short, or does it mostly short, or is it random?
This is speaking of standard resistors, I understand that some resistors intended to be used as fuses exist too.
Related, but a different question would be also can a notable permanent change in resistance occur if the resistor is 'overdriven' but not to the point of "breaking", i.e. shorting or opening? I understand that resistance changes with temperature, but don't know if a permanent change is also possible.
In case there are videos about these things that I've missed (I watched some that show resistance change with temperature temporarily, but that's all), I would love to check them out as well.
Update: I forgot to do the search first. It might turn out that this has been asked millions of times.
