Answer #1

I assume all wires are of same length andhence their resistance ( R = ρ * l/ A) is same.

Then I₁= I₄> I₂= I₃

I₁ andI₄will same as wires carrying thesecurrents are in series and current in series is same.

I₃ and I₄ will be sameas these are in parallel hence same poential difference occursacross each and have same resistance. This will result in samecurrent.

Finally current will be divided into twoequal part (I₁ = I₂ + I₃) henceI₂ and I₃ will be less thanI₁.
