Hi All,
I have been studying electronics at the Cleveland Institue of
Electronics for some time now...recently I sent them a question
concerning a wheatstone bridge, but I have not yet received an
answer...I thought I would post it here on the newsgroup so that
perhaps someone could point out my error. I am attaching my question
to this post. If anyone could point out what I am doing wrong I would
greatly appreciate it.
Thanks in advance,
Russ

Love to help you but I can't open the picture. It would also be nice if you
described your problem rather than your saying that you have one.

Good Morning Don,
I am new to posting with this newsreader, so I dont know why the
picture didnt open.
My problem is this: I am studying linear network analysis, and am
trying to set up linear equations to solve for various currents
running thru an unbalanced wheatstone bridge. I am trying to use
Kirchoff's laws to do this, but I am doing something wrong. Would it
be possible to email you a copy of my work so that you could see what
I am doing? Any help that I could get would be greatly appreciated.
Thanks,
Russ

The problem is that you've posted the html but not the picture files. You
could try saving it as an mht file instead of html, which might embed the
pictures.

No problem- glad to look at it. Have you gone beyond KCL, KVL which apply
generally, to loop and node methods which depend on linearity?

Good Morning Don,
I am using KCL and KVL, trying to set up a set of linear equations to
be solved simultaneously. I am trying to find a way to repost my
graphics and equations so that you can see what I am talking
about...and I am hoping to have this ready to post by late tonight or
tomorrow morning (I own a TV repair business, and the super bowl has
kept me jumping). Thanks again for being willing to take a look at
this for me.
Thanks again,
Russ

Here's a link to a freeware format converter that will convert the .png file
from your software to a .ico file that we should be able to see in the
newsgroup. I tried using it on the files you sent but the newsgroup seems
to have filtered them out (ie nothing there).

Hi All,
I have put my question on my website at

I believe everyone should be able to see it now. If anyone could point
out what I am doing wrong it would be greatly appreciated.
Thanks in advance,

Second equation first term should say "500(I1-I2)"
Then you'll get
I1= .021
I2= .014
I3= -.0145

Sorry -still didn't get pictures. Possibly just send a jpeg or a windows
document.
Anyhow, it appears that Jack solved your problem.
An easy way to handle a bridge is to use Thevenin.
