Calculate missing potential differences in simple series circuits.

Calculate missing potential differences in simple series circuits sits inside Series circuits, not as a generic electricity prompt. Students should first identify the safety reasoning and named wire roles that the question gives, then connect it to Series and parallel circuits using precise AQA GCSE Physics vocabulary. Key terms for this page include series circuit, and they should be used to separate related ideas such as current, potential difference, resistance, power, energy transfer, component behaviour and circuit arrangement. A strong answer states the relevant rule, applies it to the named situation, keeps units or graph features visible where needed, and avoids borrowing a rule from a neighbouring subtopic just because the wording sounds familiar.
