Homework Equations
current division: in = (Requivalence / Rn) * itotal
Requivalence in parallel = R1*R2 / R1+R2
The Attempt at a Solution
|| (parallel), and +s (series)
1ohms || 2ohms = Req1
Req1 || 4ohms = Req2
Req2 +s 3ohms
However, note that current i3,4,5 are present. Parallel elements do not share the same current. I have trouble applying the current division.
If I assume I am only taking i3, i4, and i5, and let i3 be the total current at that particular region, then the Reqv is (2*1)/2+1 meaning 2/3
Then which Rn should I take?
The formula for current division is mentioned above.
Please let me how to solve this problem that involves multiple currents going around.
Thank you.
