What examiners said
Most candidates who correctly identified the characteristics of a diode from the graph were also able to recall its name and gained full credit. Many candidates had difficulty interpreting data from the graph. Some candidates suggested that it showed current is proportional to voltage. Other candidates incorrectly stated that voltage was zero when current was negative.
— Examiner report, May/June 2025, 0972/41 Q7(a)(i) (Cambridge)
The majority of candidates who had identified a diode were able to draw the correct symbol for the component. Common errors were to confuse a diode with a NOT gate or to omit one or both connectors at the ends of the symbol.
— Examiner report, May/June 2025, 0972/41 Q7(a)(ii) (Cambridge)
Most candidates completed the circuit by adding the correct symbol for an LDR chosen from the list of possible symbols supplied.
