What examiners said
Many diagrams showed the correct symbol for the voltmeter, but relatively few candidates placed the voltmeter in the correct place. Common errors included putting the voltmeter in series or placing it in parallel across the ammeter.

Very few candidates answered this question correctly. Many appeared unfamiliar with the term focal length, in this case the distance from the centre of the lens to one of the focal points.
— Examiner report, October/November 2023, 0653/31 Q9(c)(i) (Cambridge)
A magnifying glass is not simply a type of lens, it is a converging lens that is used in a particular manner. The option that describes this use is option C and although this was a popular choice amongst candidates it was not the most popular. A slightly larger number of candidates selected option B. Very few candidates selected either of the other two options.
