What examiners said
Almost all candidates knew the correct symbol for a voltmeter, and many positioned it across the resistance wire correctly. Common errors included positioning the voltmeter in series in the circuit, in parallel to one of the components in the circuit or to represent it in parallel to the wire but with the connectors either too close together or too far apart. To be correct, the wires from the para...

Some candidates correctly identified that opening the switch prevents overheating of the wire. Danger from electric shock was a common incorrect answer.
— Examiner report, February/March 2024, 0653/62 Q4(a)(ii) (Cambridge)
When recording results in a table it is essential that candidates follow the pattern of resolution of the other values. In this case, all other values of the potential difference were recorded to two decimal places, so it was essential that a voltage of 1.10 was recorded for 45.0 cm. Many candidates did not follow the pattern, stating that this value was 1.1. Most candidates correctly gave the cur...
