What examiners said
Weaker candidates often took into account only the length doubling, leading them to choose option C.
— Examiner report, October/November 2019, 0654/22 Q36 (Cambridge)
This question on electric current was found to be challenging. A significant number opted for D, having assumed that the p.d. across each resistor was 120 V, as would have been the case had they been connected in parallel.
