What examiners said
Many candidates understood that the currents in the parallel branches add to give the current in the main circuit and were awarded full credit. Some candidates did not realise that this was a straightforward question and attempted complicated calculations involving resistance in parallel circuits even though no values of resistance were given.
— Examiner report, February/March 2024, 0653/42 Q6(c)(ii) (Cambridge)
This question was answered correctly by some candidates. Incorrect responses included descriptions of the wires being covered with rubber and the effect of heat on them, and changes in height of the poles.
— Examiner report, October/November 2023, 0653/33 Q6(c) (Cambridge)
Most correctly recorded both readings. 1.8 A as the current Is was a common incorrect answer.
