Hi Jay,
"now you know what equations am using can you help me ?"
As this clearly is a work assigned by your university it's your job to do the programming.You want to get a university degree, so please do the work needed to get one!
Up to now you did not attach any VI nor did you show any pictures of a block diagram... I will not do any programming work for you and I hope no one else will do. But we will always be happy to assist with code reviews and hints on what to do. You should have noticed all the comments given on your work task.
Please do some work on your own and be assured to get more help for specific problems.

Sir,
Am simulatenously working on the .VI. I know the rules and will not go against them. I certainly will do my part of programming. I will soon, very soon post my 1st .vi
Thanks Sir 🙂

This is the VI which I implemented using the above mentioned 3 equations. The loop is working fine. But then the graph is coming to be a strainght line. Please help. I know this is a very basic try .

Yeah, I figured out the indexing problem. The for loop how and why ?
Now for the XY graph why after 25 is it going backwards. Can you explain me that slope reason !

Sir, But why the slope in the XY graph after 25. I need to remove that then for a given value of Ib 20ua the graph in XY is proper but the backward slope.
The equtions are the ones we study and use. What changes in them you think?
And the array points, I checked it using the bulb tab or the highlight execution tab

The slope appears to be going backwards because that's the data you're plotting!
Check out the data outputted from your equations and you'll see the reason for the slope:

[EDIT] Sorry for the double post - you beat me to it Gerd!

Now is this ok ??

Well, all you've done is remove the last 3 data sets from the arrays above! I don't really think this is a solution.
I agree with Gerd - are you sure your equations are complex enough to describe the transistor behaviour?
-CC
