Some day this student may be designing a circuit for your car or expensive plasma TV. Do you really think it's wise to be doing their homework for them?

Dennize - it would be better if you worked out the problem, and then asked about your results if you aren't sure about them.

An answer has been given, but how was it obtained? Is it correct? How do you know?

 

[jallem]

You are so smart that is overwhelming.....!!!!!!!!!!!!!

To House_Cat,

I absolutely agree with you. I thought the same and then read your text.

to housecat:

i know how to solve this problem using mesh analysis but the only problem is how to solve the unknown A? in the given independent source,,and by the way the only given in this problem is the voltage drop at V2 and V3,,did you see that,,how are you going to solve this in oder way using nodal analysis,tnx

Added after 5 minutes:

to jallem:

tnx for the answer but i nid the solution,,can u pls show me the solution??how did you solve that??what particularly technique did you apply in that equation,,,are you using mesh analysis or nodal analysis techniques???tnx,,pls reply asap

You know that is exactly the place I wanted you to be. In others
words, the underlining issues here are the following:
1) You are not a lazy student who need to deliver a homework, for
what I can see you did study, you worked it out, you know the
techniques to solve it, and you are looking for more information.
2) That does not mean you are going to be a stupid engineer making
stupid design as someone said.
3) I did not tell you the process to come up with the answer.
4) The problem itself is just a stupid question for someone who believe
that being smart is more important than work hard. I will explain it later.
Just see this:


5) The problem does not ask you to solve for A. I did not solve it either.
6) The problem has a trick, and that does not means you are going to be
a better engineer or not if you solve it, it is just a trick, and that is what I
do not agree with those kind of questions. It does not test how much the student
work or the kind of training the student is receiving, it is just testing how smart
is the question or how smart is the professor asking for it.
7) I was once a professor but more importantly I was a student, now I know
the tricks. But that does not means you will be a bad engineer just because the
tricks are showed to you earlier.

With all that said I am going to tell you just his, the secret is in the minus sign.
You figure it out.. Let me know if you do....

For the others fellas, I could not care less for what you can say......

For the others fellas, I could not care less for what you can say......

I doubt you ever were a professor. One as arrogant and sarcastic as yourself could never keep a job at a university.

You also have difficulty reading and understanding. Nobody attacked you or your original post. All I did was post an opinion regarding what was necessary from the requestor. He has done what was asked in my post - he has demonstrated an effort to solve the problem on his own.

Come down from your high horse, and play nicely.

 

[jallem]

Like I said: I could care less for what you can say..
By the way......what was the issue?...In other words,
Is there anything I said that you took it personally?
The poor kid would feel confused......
I am sorry, no one is more arrogant but the one who
can attack personally for something others believe.

Goodbye, there is not more "INTELLIGENT" discussion
with you.

By the way, IT WAS JUST MY OPINION ALSO.........

I doubt you ever were a professor. One as arrogant and sarcastic as yourself could never keep a job at a university.

Was that a PERSONAL attack?..... Wow. I did not see it coming....

That is contradiction, arrogant are the only one who can keep a job at the
university, just like the one who ask the question or the ones who defend
the question.

 

[House_Cat]

Was that a PERSONAL attack?..... Wow. I did not see it coming....

Really?....

You are so smart that is overwhelming.....!!!!!!!!!!!!!

ei jallem,

i can't get the answer you gave to me,, i try to solve this,,,pls i know that you know this,,,can you pls show me the solution so i know where part of solution i go wrong,,pls,,,i nid your help,,and its my pleasure if you help me,,,thnaks for answering my question,,i am looking forward for you reply and help,,thanks a lot,,

You're not looking carefully enough at the problem.

What is the voltage across the 5ohm resistor? Write it down.

Now look at the voltages around the outside of the mesh. Two of the voltages are given to you (v3 and the voltage across the 1F capacitor).

You said you knew how to do mesh analysis. If you simply write the voltage relationships around the outside loop of the mesh, you'll have your answer.

Post again if you still don't see the answer.
