Short explanation

Apply WS 1.4 when explaining the efficiency of power transmission sits inside The National Grid, not as a generic electricity prompt. Students should first identify the diagram symbols and connection order that the question gives, then connect it to Energy transfers using precise AQA GCSE Physics vocabulary. Key terms for this page include efficiency, 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.
