    Ahem. "Original Poster".

  2. This is the first time I have heard that interpretation of OP, and I
    have heard the expression "the other person" at least a few thousand
    times here in usenet. But I have nothing against that interpretation, it
    sounds plausible too.

    "other person"

    "original poster"

    That's funny, a search on groups google seems to support your
    interpretation stronger than mine. :)

    Maybe this is a suitable occasion to quote Isaac Asimov:

    "The most exciting phrase to hear in science, the one that heralds new
    discoveries, is not 'Eureka!' (I've found it!), but 'That's funny..."

    It wasn't the term beginner that made it seem condescending to me, it
    was the assumption that because I was a beginner in electronics, that I
    was incapable of comprehending a "real" explanation. The mathematical
    relationship that another poster gave was a much more useful and
    succinct explanation and gave as good of in site into why you need to
    regulate the current as I think you could have. After all isn't the
    reason we use news groups because we want a quick answer and don't want
    to take the time to "read the book"?

    A quick look at the from header in the message would tell you that I am
    the one who started this thread.
    somewhere in between would probably be a better fit for me.

    When I respond to NG posts I generally try to get a feel for what the
    poster already knows, and gear my reply to that.

    Well anyway I think you should use a pressure relief valve instead of a
    damn for your analogy. Having some experience in hydraulics, that
    sounds like a better fit. Of course, like any analogy, if you try to
    take it too far, it will fall apart as well. One of the reasons I like
    the pressure relief valve is, just like an LED, if you pass to much
    current through it, it will get hot fast. Then you could also relate a
    current regulator to a pressure compensated flow control valve, but that
    is starting to get too deep into hydraulics, unless of course you are
    already familiar with hydraulics.

  4. Restricting the search to this newsgroup gives the numbers 48 and 50.
    Still to your advantage but at least a lot closer to fifty/fifty.
  5. Very few people who ask questions here are able to read and understand such a
    mathematical expression. If I recall correctly you even got a comment as if
    your simple acceptance was sarcasm. That was another person who did not
    expect a mathematical understanding at that level from you. So I wasn't
    alone in misjudging you.

    looking up and quoting:
    You forgot the smiley...

    An analogy for a diode in general is a wall in a tube with a door which
    opens only one way. That model allows for many properties of a real
    diode, like backward leakage, backward breakdown, exponential forward
    conduction (if the door is kept shut by a spring), etc..

    I think such analogies are valuable for beginners, others say they are
    more confusing than enlightening, and they think the math expressions are
    better for beginners.

    If it were "Other Person" it would be too ambiguous to make any sense.
    Which "Other Person" on the thread for instance? It could be anyone.

    On the other hand, "Original Poster" is very specific and refers to
    the person who started the thread, the original poster.
