    I'm not confident at all about my equations.. -Va*(G4+G03+G3+G2+G02) + Vc*(G2+G02) + Vb*G4 = -E3*(G03+G3) + E2*(G2+G02) -Vc*(G5+G02+G2+G6) + Vb*G6 + Va*(G02+G2) = -E*(G02+G2) -Vb*(G4+G6+G01+G2) + Va*G4 + Vc*G6 = - E1*(G01+G1)

    Yes, there was my mistake with KLC. Please, can you write equations with KCL for the nodal method if you didn't like my equations with Kirchoff Rules method?

    I just have a requirement to use KLC method to solve the task. Or I can use KLC method in other task, but then I have to use nodal method for this task. I less understand nodal method, but we can try to find solution.

    I finish this task: I1 = (fi1-fi3+E1)/R1 = (-8.2877-21.6043+18.8)/523 = 0.0212 A I2 = (fi2-fi1)/R2 = (0.0185-(-8.2877))/295 = 0.0282 A I3 = (fi3-fi2)/R3 = (21.6043-0.0185)/766 = 0.0282 A I4 = (fi1-E2)/R4 = (-8.2877+19)/217 = 0.0494 A I5 = (E3-fi3)/R5 = (38.1-21.6043)/334 = 0.0494 A I6 = fi2/R6 =...

    Despite that I believe, that solution in post #14 is wright. I tried to solve it with KCL method. I1*(R5+R01+R1) + I6*R6 = E1 -I6*R6 + I4*R4 + I2*(R02+R2) = E2 -I2*(R2+R02) + I3*(R03+R3) = -E2-E3 A] -I2 + I4 - I3=0 B] -I4 - I6 + I1 =0 C] -I1 + I6 + I2=0 I didn't include I01, I02, I03, I5...

    Actually, there is no need for other method if Loop Current Analysis equations were right. [as you mentioned]. I just wanted to be sure, but I will believe and hope, that there is all OK. But when we reconnect voltmeter, we get that diagram or not? I guess that bottom corners are nodes...

    30+50=(0.2+3.8+2.9+0.2)*Ia - (0.2+3.8)*Ib 40=(4+5+3.9+0.1)*Ic + (0.2+3.8)*Ib -50=(4+4+3.8+0.2)*Ib-(0.2+3.8)*Ia + 4*Ic I solve that system and get: Ia = 10.127A Ib = -2.024 A (I guess, there is opposite current direction) Ic = 3.7 A Then: I3=I03=Ia = 10.127A I5=I1=I01=Ic = 3.7A I6 = -Ib-Ic =...

    Thanks! But I also have to calculate currents with Loop Current Analysis for that loop, when switch is ON: Here I have example, but still I'm not sure, how to write these equations correctly: I guess it can take just a minute for you. I tried something like in example...

    Please, can you tell your solution with nodal method or at least give me a few hints? Actually, I have calculated this task with Kirchoff's Rules method (as you saw my answers), but there is needed Nodal method as well to be sure with my solution, but I don't know how exactly I can get it with...

    I count R03+R3 = 0.1 + 3.9 = 4, same as R01+R1 = 4 (let it be R3 and R1, but just without R01 and R03) Then: I6R6+I3R3+I4R4 = E3 -I1R1-I5R5-I6R6=-E1 I6-I1-I3=0 As I5=I1 and I3=I4 (as you metioned), then is system of: 10I1+3I6=40 9I3+3I6=28 I6-I1-I3=0 When I solve it, I get I1=I5= 2.7A; I3=I4=...

    Heh, I don't know what, but I did something wrog. I tried Nr.32 using Kirchoff's rules analysis/method. I got system of: I5+I1-I4-I3-I6=0 I6-I5-I1=0 -E3=I3R3 - I6R6 + I4R4 E1 = I6R6 + I5R5 + I1R1 A, B - nodes. What I did wrong? And also do I have to count R1+R01, R2+R02 and R3+R03 to get R on...

    Yes, R01, R02, R03 are internal resistances. But why there are four loops? Maybe I don't understand something, but I guess, that, when switch is OFF, then we don't have to use R02, R2 and E2, and of course we don't have to use voltmeter. And then there could be two loops like this: Or am I...

    I have to calculate 1. current in each branch, 2. voltameter result 3. electromotive force (EMS) mode and 4. power bilance. And need to use four methods: Node Voltage Analysis (Node potential method) Superposition Method Loop Current Analysis Kirchoff's Rules Analysis I hope you can...
