In the circuit shown, all the resistors are identical and all the ammeters have negligible resistance. The reading A₁ is 0.6 A. What are the readings on the other ammeters?

1. AA₂ = 1.0 A, A₃ = 0.3 A, A₄ = 0.1 A
2. BA₂ = 1.4 A, A₃ = 0.6 A, A₄ = 0.2 A
3. CA₂ = 1.8 A, A₃ = 0.9 A, A₄ = 0.3 A
4. DA₂ = 2.2 A, A₃ = 1.2 A, A₄ = 0.4 A
