(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In the circuit below find the current I3 (in A) when R1 = 26 Ω, R2 = 52 Ω, R3 = 36 Ω, R4= 25 Ω, R5 = 162 Ω, and V = 80 V.

Be careful about the sign.

2. Relevant equations

I=V/R

3. The attempt at a solution

I tried to solve for Req...i don't think i'm doing it right though. I calculated R2 being in parallel with R4. Then I said that answer was in series with R1 and R3 (no idea if that's right). Then i said that answer was in parallel with R5 and got Req to equal 53.05Ω
