Homework Equations


KVL/KCL


The Attempt at a Solution


Meshes for;

Loop 1
20 = 6i1 - 4i2 - 2i3

Loop 2
-4i1 + 18i2 - 8i3 = 0

Loop 3
2i1 + 8i2 + 6i3 +10i0 = 0



For the life of me I cannot get -5A as the answer. I have tried the following for i0;

i0 = i1 - i2
i0 = i2

And neither give the correct answer (-5A). Help please! trying to get this down and subsequently superposition/thevenins and nortons theorem down for an exam next week

Your Loop 3 equation looks suspicious. I don't see the sum of the loop resistances as a coefficient for i3, and there should be sign changes for some terms.

io = i2 is fine.
