Would resistors short itself?

    usually they act like fuses (if abused)
     
  4. 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.
     
  7. I counted 3 more trolls here.

    Do you three wanna talk about resistors or not? Or do you just wanna
    pull your guns? :)

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

  9. I don't care about their ranks! I come here to learn more about
    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
    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
    have any obligation to help you understand electronics.

    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?

    Did you enjoy spanking others while being a kid?

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

  14. 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.
     
  18. Now we got 3+1+1? :)

    ** My god, now the slanty eyed Chink is a maths genius too.

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

    That joke is just as old as the earlier one -

    like 100 years plus.
