What examiners said
There was an error in Question 12(a). The question should have stated: ‘Fig. 12.1 shows a 10 Ω resistor and a resistor R of unknown resistance connected in parallel with a 1.8 V cell.’ This has been corrected in the published version of the paper. Due to this issue, full marks have been awarded to all candidates for Question 12(a)(i) to make sure that no candidates were disadvantaged.
— Examiner report, May/June 2025, 0973/41 Q12(a)(i) (Cambridge)
Most candidates recognised that the current is the same at any point in a series circuit.
— Examiner report, May/June 2023, 0973/42 Q9(a)(ii) (Cambridge)
The correct response was that the ammeter was connected in series. However, many candidates described using wires to connect the ammeter to the circuit. Many candidates also suggested a parallel connection.
