What examiners said

Most candidates were able to correctly read the voltage and calculate the time from the ECG.
— Examiner report, October/November 2023, 0653/62 Q1(b) (Cambridge)

Most candidates found this question straightforward. Some candidates selected option D, indicating that the glucose facilitated the transfer of light energy to chemical energy.
— Examiner report, May/June 2023, 0653/22 Q4 (Cambridge)

The correct option, B, was the most frequently selected and candidates that chose this value had calculated the current in the appliance and realised that the most appropriate fuse rating was one that is greater than this value but not hugely greater.

Know that electric current is related to the 5 Define electric current as the charge passing flow of charge a point per unit time; recall and use the equation Q I= t
Understand that electric circuits transfer energy from a source of electrical energy, such as an electrical cell or mains supply, to the circuit components and then into the surroundings
State that positive charges repel other positive charges, negative charges repel other negative charges, but positive charges attract negative charges
