Figure 4 below shows a part of an electric circuit.
(a)[1.0]
Apply Kirchhoff’s junction rule to the junction A to find current flowing through the $5\,\Omega$ resistor.
(b)[1.0]
Apply Kirchhoff’s loop rule to the loop ABDA to find current flowing through the $7\,\Omega$ resistor.

From ISC 2025 Specimen Physics Paper 1, question 4(i).
Check your working with the Circuit solver (Kirchhoff's laws): every current, p.d. and power in a circuit of cells and resistors; equivalent resistance too.
