Mark - just a slight detour from this thread's main theme, since you mentioned it - voltage rating of resistors.
This is something that I've never really got down to understanding the full 'nitty-gritty' detail of. Conceptually, yes, I can easily understand that a resistor must have a voltage rating, above which the resistor will fail - and in a particular way - perhaps by simply flashing over from end to end.
But I suspect that the importance of the voltage rating of any particular type of resistor construction goes far beyond that. So, in summary, for the various types of resistor construction that are commonly available, what happens - short, medium and long term - if that voltage rating is exceeded? Or, to put it briefly, what is the importance of voltage rating in resistors, and why?
Thanks,
Al.
