2. Relevant equations

V = IR

Rseries = R1 + R2 + ... + Rn

Rparallel = (1/R1 + 1/R2 + ... + 1/Rn)^-1

3. The attempt at a solution

I simplified the circuit, to find I = 3mA. What I did was this (in order starting from far right):

6||3 = 2kohm, which is in series with 16kOhm, so 18kOhm.

The 18kOhm is in || with 9kOhm, so 6kOhm.

6kOhm is in || with 6kOhm, so total of 12kOhm.

The 12kOhm is in || with 4kOhm, as well as the 6kOhm. So I got 2kOhm for that part.

Then, then 1kOhm and the 2kOhm are in series, so that equals 3kOhm total equivalent resistence.

Then, I found that I = 3mA.

Now, it says to find I_0. I have no clue as to how to do this. I think my simplifying is correct.
