For my curiosity!

usually they act like fuses (if abused)

If you apply too much voltage, the voltage could arc around the resistor.
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.

Is it just me or does anyone wonder why this guy is obsessed with
components shorting. Maybe he has a different definition of shorting.
Oh well, back to my ale.

8. Mr. Man-wai ChangGuest

I counted 3 more trolls here.

Do you three wanna talk about resistors or not? Or do you just wanna

They aren't, but even if they were trolls, they've been around here long
enough to have seniority.

resistors and previously LEDs.

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

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

search. A lot of the gap in your understanding could be filled by

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

12. Tom BiasiGuest

I have no intention of bullying you or anyone else. You have been given
much help but you persist in asking the same thing over and over about
components shorting. What's your definition of a shorted component?

I represented nobody but myself!
Did you enjoy spanking others while being a kid?

What's wrong about looking at a problem from different perspectives? I
could discover something new doing so, notably discrepancies.

I didn't. And I knew that once you 3+1 called the shots, you 3+1 would
not leave me alone, not even after I left/died.

Yup, I've seen this happen to carbon comp bleeder resistors across mains
filter caps as well. Eventually, as the resistance decreases enough, smoke
ensues.

Now we got 3+1+1?

Ever hear about the dumb blonde who thought "ping pong" was a smelly

That joke is just as old as the earlier one -

like 100 years plus.
