have already done that, but the results don't match with the results that i got in multisim so i want to see someone solving the circuit in order to understand what i did wrong.Hi,
Start by choosing a ground (0v) node and numbering the others 1 through N.
You need to show YOUR best work to solve YOUR homework. That way we can see what you did right and where you might be going astray so that we can help nudge you back onto a good path.
Since my crystal ball is in the shop, I can't see what results you got in multisim, so I have no idea whether they are right or not. Nor do I have any clue as to where and how they agree and disagree with what you got.have already done that, but the results don't match with the results that i got in multisim so i want to see someone solving the circuit in order to understand what i did wrong.
The only thing i need to know is the u3, node 3 voltage and u2, node 2 voltage.Since my crystal ball is in the shop, I can't see what results you got in multisim, so I have no idea whether they are right or not. Nor do I have any clue as to where and how they agree and disagree with what you got.
The only result I see in your work here is that V3 = 130.5 V.
What about the rest of the voltages and currents?
Are those results selfconsistent, or are they contradictory?
I have already done that, and thats why i'm asking for help.Similarly, look at the simulator results for all of the node voltages and branch currents and see if those are consistent with the problem. If they are, then you can have confidence in them. If not, then there is something wrong with your simulation (usually meaning that the circuit you simulated doesn't match the circuit in the problem).
If you've solved the circuit many different ways, then it should be a trivial matter to post what you got for the node voltages and branch currents, shouldn't it?I have already done that, and thats why i'm asking for help.

.... i dont need more questions... i just need a solution... i tried everything i know based on what i learnedIf you've solved the circuit many different ways, then it should be a trivial matter to post what you got for the node voltages and branch currents, shouldn't it?

i dind't do that, if you look better, you can see that i wrote i=U3/3...Hi,
Quick note here...
The current 'i' is not equal to 3*U3, it is equal to U3/3. Try using that info. That's Ohm's Law.
So what you learned doesn't allow you to find the voltages at all the nodes and the currents in all the branches?.... i dont need more questions... i just need a solution... i tried everything i know based on what i learned

i checked all the voltages and currents and i've solved other problems with this method.So what you learned doesn't allow you to find the voltages at all the nodes and the currents in all the branches?
In other words, you aren't interested in learning how to check your work, you just want someone to do your work for you.
Thank you for at least finally posting your schematic so that at least we can stop trying to do mind reading on that point.
In the original circuit, the current that is controlling the dependent source is the current going THROUGH the 3 Ω resistor, right?
In your Multisim simulation, is the current that is controlling the dependent source going THROUGH the 3 Ω resistor?
thank you!Hi,
Oh yes you are certainly correct. I didnt see that part up there. I'll make a somewhat more clear drawing.
I'll also take another look too.
I solved the circuit in about two minutes. I even told you what the power being delivered by the dependent source was so that YOU could check YOUR work.i checked all the voltages and currents and i've solved other problems with this method.
you can see in the photo that I wrote a lot in that paper and obviously it's not "not want to work".
if i could help someone solving a circuit like this i would not mind to, at least, writing the main equations to the exercise.
You can see my main equations, and based on the circuit you can see if you agree with them or not. It's all that i needed.
And this is not a work, it is an exercise that I want solve alone, but I can pass this one and ask my teacher then.
I just wanted to answer it because it is driving me crazy not making it right.
So if you're not able to help ... or say something about my equations because you dont know my way to use this method, dont say anything at all.
Someone who understands this kind of stuff can solve it easly and I'm sure I saw it in this forum. People have done that.
And yes obviously the current is controlling the dependent source and you didnt need multisim's schematic to know, is in the previous image.
