Homework Equations


Assume we have Vab.
Junction Rule:
I1 = I3 + I4 => I'1 = I'3 + I'4
I5 = I2 + I3 => I'5 = I'2 + I'3
Loop Rule:
V - L1I'1 - L4I'4 = 0
-L1I'1 - L3I'3 + L2I'2 = 0
V - L1I'1 - L3I'3 - L5I'5 = 0
V - L2I'2 - L5I'5 = 0

The Attempt at a Solution


First I tried 2 junction equations and 3 loops without V. Then I eliminated to the last 2 equations with 2 unknown, but I got 2 same equations.
Now I try with the equations above and still got 2 same equations.
I'm thinking maybe it's not write to say that I1 = I3 + I4 => I'1 = I'3 + I'4.
I need some suggestions about what loop should I use.

I have that problem too! we had a group of hella people from 2 physics 421 classes working on that! we didn't get an answer, any new luck?
 
Come Back Online! I am with a study partner trying to figure this out! we can ConVerSate! Share Ideas! ! ! !
 
ε=Leq[1/[(1/di1)+(1/di2)]]
 
Sorry I don't have any idea yet. Are u from Shiwen class also?

Yeah, this question blows! we've worked it more than a dozen ways with more than a dozen other people! but the rest of the problems were easy
