A circuit is constructed with five resistors and one real battery as shown above right. We model. The real battery as an ideal emf V = 12 V in series with an internal resistance r as shown above left. The values for the resistors are: R1=R3 = 58Ω, R4 = R5 = 77Ω and R2 = 136 Ω. The measured voltage across the terminals of the batery is V_battery = 11.62 V.

What is the current I1 and the internal resistance r.
