In Reply to: Resistor break-in: how is this possible? posted by LowRedMoon on November 8, 2006 at 14:18:35:
You are seeking a physical answer to a perceived phenomenon; you are asking why. I'm interested to see if anyone can provide a plausible answer for metal films.For carbon comps, I've read that they can change value permanently or temporarily when exposed to high voltage, heat, humidity, etc. And there's a physical explanation: solid carbon exists in several ways (I think they're called phases), and some of the carbon can change phase or whatever it is. That would certainly change resistive value, and could even change sound if, for instance, one phase has something of a piezo quality. (Wouldn't it be nice to find a way to cheaply change to diamond phase?)
