In my experience resistors fail open, not short. Usually what happens is
that some resistive material burns away, that forces the surrounding
material to carry more load which makes it hotter, and then the rest
burns away.

There may be some resistive material out there that leads to the resistor
failing short -- but it'd have to be a weird construction out of a weird
material.

Maybe in Oregon. It's illegal in most other states.

If you apply too much voltage, the voltage could arc around the resistor.
Click to expand...
That's why high voltage probes that need a very large value resistor
either use very special resistors intended for the purpose, or a string of
resistors, so if there's arc-over, it won't go around the full value of
the resistors in series, just around one.

** Not likely at all.

Nearly all resistors are spirals of material (metal, carbon or composites)
around a ceramic rod - so any breakover will be between adjacent turns in
the spriral. This will probably ruin the part but it will not short end to
end.

A series string of resistors breaks the voltage applied to EACH resistor
down by the number of resistors, making much higher voltages tolerable.

They almost always fail open.

In the old days of carbon composition resistors they might fail
shorted (or going lower in value) on rare occasions. This seemed to
be a problem unique to vacuum toob circuits where high voltage DC is
continuously applied across a high value carbon comp resistor. More
often than not, it would be a "screen" resistor, probably because
even with reduced resistance the current flow was minimal, and not
enough to cause it to burn.

Break the shells open and you could see where it appears as if some of
the copper from one lead has migrated into the carbon mixture. This
type of failure was extremely rare.

I don't care about their ranks! I come here to learn more about

So take this bullying crap back to your US schools and maybe military

They may be trolling/bullying, or they may simply be fed up. You have an
apparent unwillingness to learn basics for yourself, or to listen to the
advice given free of charge.

Anyway, a lot of your questions could be answered quickly by a Google
search. A lot of the gap in your understanding could be filled by
reading a text book.

Did you ever perform the experiment I suggested about LEDs? A little bit
of lab experimentation beats the hell out of a text book and Google :).

Oh, and for the record, whether your intend it or not, your posting
behavior *appears* trollish. I'm not sure what advice I can give to you
that would help you avoid that, but perhaps just being aware could help
you. We are here because we like to discuss electronics, not because we

"Mr." Man-wai Chang is representative of what I see as an alarming
increase in these groups... "punks"... ignorant as a stump, but
pompously considering themselves as superior beings.

If someone can locate "Mr." Man-wai Chang's kindergarten they should
give him a good spanking >:-}
