Correct symbol for a transistor? (URGENT!)

R

Guest
Hey guys,

Long time lurker, first time poster - just needed the right excuse to
post on the boards, and one presented itself just last week.
I recently completed a simple physics test worth 5% of my final year's
work, a gift in my opinion. However, I only achieved 26/27, for a
reason I'm not sure is correct. I hope that my asking the educated
here, I can prove my case.

Basically, the question asked to draw a simple circuit, and within
this circuit was the symbol for a transistor. So I complied, and drew
it in, arrow pointing outwards (NPN transistor), and labelled the pins
(B,C,E). Now the transistor has a circle around it, and my circle was
drawn perfectly, BUT the tip of the arrow was not touching the edge of
the circle, and hence a mark was taken off. IS THIS FAIR? Is it
strictly defined to have the arrowhead touching the edge of the
circle?

Any help would be appreciated, and if you know of any creditable sites
I can vist (that prove or disprove my case), it would be most helpful.
Cheers,

-Raoul

Assuming the base collector and emitter are correctly labeled and the

symbol was correct:

No the arrow has no business touching the circle, few people even draw
a circle any more. The course is physics and not electronics so the
professor may be out of his/her element.

I looked at a sampling of my electronic books and did find one where
the arrow was awfully close to the circle, most (where they did draw a
circle) were well inside.

How does this guy draw a darlington transistor or PNP?

Most colleges are not designed to impart understanding, just
knowledge. One of the things they are there to teach, is that you
don't rock the boat. Right or wrong doesn't matter, do it their way.
When in college suppress thought, you only have to memorize, look
intelligent, look interested, and make the professor happy.

did others achieve 27/27?
bet nobody did.
faculty is reluctant to "give away" perfect scores.
we had a saying:
"the author of the book gets the A (90 to 100%).
the proffesor gets a B (80 to 90).
the teacher's pet gets a C (70 to 80).
the rest of the class battles for the D(eficient) and F(ailed)."

These days the author of the book is the professor - little extra
income for the prof and college that way

Roger that

In Raoul's position, I might try to go to the library and pull a stack
of books and copy the pages containing NPN semiconductors to prove the
point, but that's like pulling a pistol and taking careful aim at
one's foot.

Sure I might beat the prof into submission on this one point, but if
the insecure little bastard felt humiliated, he'd make it his business
to see that I flunked the course - and it just isn't worth it.

You go to college to get a very expensive piece of paper. That should
be your primary goal and you should be satisfied with that. If you
happen to actually learn something that's gravy, but don't count on
it. When you are finished with college forget almost everything, and
start learning.

College serves very useful functions: It keeps young adults out of
the job market, provides jobs to college graduates that never do learn
to think, is an expensive form of adult day-care, removes any
creativity (assuming some made it past high/prep school), makes
exemplary consumers out of people - that left to their own devices,
might become dreaded "free-thinkers." Ivy league colleges serve the
additional function of separating the ruling elite from the rest of us
dregs.

One can learn useful things in college.

I was being facetious. Seems a little nit picking to reject the
transistor because it is drawn in an accepted conventional way. Had
it been me, I'd be livid.

Like an English composition class I took. My short story had a pilot
and copilot crashing. They knew they only had seconds to live. I
added notes to the end detailing all the places I (my characters) used
incorrect grammar and what would have been correct.

I still got marks off. Went to the dean with it . . . he talked me
out of pursuing it since the particular instructor was already in
jeopardy.

answered some of the questions incorrectly.

And I think that is actually true 80% of the time.
 
You're kind of between a rock and a hard place. If the grade is going to
make a difference in your final grade, I would do as someone else said, get
a pile of books from the library with the symbol drawn the way you did it
and take it to your instructor. If he won't budge, go to his supervisor.
Whatever you do, do it in a nice way with a smile on your face, and just
explain it seems there are several ways to draw a transistor, and you feel
your drawing is well within excepted practice. In other words, both you and
your instructor are correct, and thank the instructor for allowing you the
opportunity to see there can be several acceptable ways to present the same
thing.

I once saw a kid's math test where 3 divided by 0 was equal to 0, 0 being
the correct answer. This was a standardized test, and I could not convince
the teacher that the answer was incorrect. It took four letters from the
math department heads at four different universities to get this changed,
including going well over the head of the teacher. Nobody would believe me,
and sometimes they just don't get it.

I'm by no means an expert on anything. In my attempts to get
retrained/re employed post brain injury I know a lot about tests and how
they can be used against you. My first question is what was the purpose
of the test? Was it to test your knowledge of a particular circuit,
your illustration skills or both? Far the most part neatness is an
expectation, however IMO expecting perfect free hand drawing is
unreasonable. Is your instructor being fair? Probably not, but I doubt
that approach will get you far. Not much help I know, I wish you luck
in changing the instructors mind Raoul.

Talk to your instructor about it. Perhaps the mark off is not for what
you think it is......
