Thank you all very much. I have an AS in electronics and have been working as a tech for years, but I am forced to use alternative methods to solve circuits now while pursuing my EE degree. If you want to degrade me and ask if I know anything about this subject that's unfair. If I was as stupid...

Yes, why isn't i4 equal to V2/6 if i3 is equal to V2/2? Is it because i4 is not part of the supernode?

Yeah, R is resistance. Is this because i4 is not included as part of the supernode? i3 is equal to v2/R3, so why isn't i4 equal to v2/R4?

Alright thanks! But now I have a more baffling aspect to consider: why is i3 equal to v2/r and i4 equal to (v1+6)/r?

Yes I meant mV and I do know the difference thanks. I have tried so far: I1=i2+i3+i4 I1+i2+i3+i4=0

Hi, V1 for this problem is 400mA and no matter how I work this problem I cannot get the correct answer. V2=V1+6 For the second equation, I don't know what to do with 14V. I've tried subtracting it from V1 divided by the 4 ohm resister, most logical, and that doesn't work. I've tried multiple...

None of this helps. I have tried this problem 11 ways to Sunday and still cannot arrive at the correct answer! This is a chapter intro PRACTICE problem and is not for homework or for a grade. I simply want to know how to solve this thing.

I used the formulas you suggested and still cannot get the correct answer. The book says v1=7.608 v2=-17.39 v3=1.6035 Any further help will be greatly appreciated - I have spent hours on this problem

I already found those values. I have 3 of the 4 equations I need and I can't understand how to find the formula for the V1 node. there is i4 and i1 coming out, but nothing going into the node. Here are the formulas I already found: V2=V1-25 V3=V2+2.5V1 2V1-3V2-6V3=0

I can't tell you how many attempts I've had at this. I must be following the current wrong, or something... PLEASE HELP.. this is an example from the chapter! I feel very stupid...

Yes, we are simply finding the currents in the circuit. I'm just having a hard time understanding how the current divider is being used.

I understand the current divider and generally comprehend what this professor is saying. BUT, I do not understand why to look only at I3 in the top circuit and look at everything except I4 in the bottom example. I1= I2/I1+2 so looking at I3 makes sense to me in the first example, but it...
