See it on the paper →Which car is supplying the most useful power?
See it on the paper →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, 0654/41 Q12(a)(i) (Cambridge)
The correct answer was 0.6 A. Many candidates suggested 0.3 A or 1.2 A.
— Examiner report, May/June 2023, 0654/33 Q9(a)(i) (Cambridge)
The correct answer of 2.4 V was rarely given. A common wrong answer was 2.0 V. Few candidates suggested that unit was the volt (V). Ohms and amps were far more popular.
