When you download a "Kirchhoff's laws questions and answers pdf a level" document, the answers can sometimes look confusingly long. To avoid getting lost, follow this standard algorithm:

A7: K1 requires ( I_1 = I_2 + I_3 ) if I₁ enters, I₂ and I₃ leave. ( 2 = 1.5 + 0.5 ) → Yes, possible.

In the circuit shown:

This is a direct consequence of the Conservation of Charge . Electricity consists of electrons, which cannot be created or destroyed. If 5 electrons enter a junction, 5 electrons must leave it. Current does not "get lost" or "pile up" at a junction.
