Kirchhoff's laws — practice question

In the circuit diagram, every resistor is identical and each ammeter has negligible resistance. The reading $A_1$ is $0.6\,\text{A}$. What readings do the other ammeters show?

  • A$A_2 = 1.0\,\text{A},\; A_3 = 0.3\,\text{A},\; A_4 = 0.1\,\text{A}$
  • B$A_2 = 1.4\,\text{A},\; A_3 = 0.6\,\text{A},\; A_4 = 0.2\,\text{A}$
  • C$A_2 = 1.8\,\text{A},\; A_3 = 0.9\,\text{A},\; A_4 = 0.3\,\text{A}$
  • D$A_2 = 2.2\,\text{A},\; A_3 = 1.2\,\text{A},\; A_4 = 0.4\,\text{A}$
