Step 1: Inspect the network. The source diagram reduces its balanced inner branch to an equivalent series branch containing 8/3 Ω. Step 2: The remaining series resistances in the reduced diagram are 1/3 Ω, 1.5 Ω, and 5.5 Ω. Step 3: Rₑᵩ = (1/3 + 8/3 + 1.5 + 5.5) Ω = (3 + 1.5 + 5.5) Ω = 10 Ω. Step 4: Using Ohm’s law, I = V/Rₑᵩ = 5/10 = 0.5 A. Final answer: Battery current = 0.5 A, Option B.
