Core finding

This Electric Circuits syllabus point appears in 7 WPH12 papers across 2021–2026, contributing 7 topic questions and 7 marks. The most recent appearance is WPH12/01 January 2026. That equals 2.6% of the 268 topic questions and 1.1% of the 634 marks tagged to Electric Circuits. Only parts tagged to this subtopic are counted, so a four-part question can contribute one item and one part's marks. The table lists every matching question, its tagged parts and marks, with a link back to the paper page. Sessions are newest first, so the statement can be traced back through the full paper history.

Topic question rules and edge cases

How many topic questions cover this syllabus point?: 7 question stems cover this subtopic across 7 papers, but only 7 tagged parts and 7 marks belong to it. Other parts of the same questions are assessed under different statements and are excluded from this page.
Which papers include this subtopic?: The table lists every matching session from 2021–2026. Each row links to the question anchor on the paper page, where the full paper context and practice entry point are available.
Why can one question appear under several subtopics?: The parts of one question can assess different syllabus statements. Each part is counted under its own subtopics, so the same question stem can appear on several subtopic pages while each page lists only the parts and marks tagged to that statement.
Can I practise these questions with AI marking?: Yes. Open a paper from the table and use the Interactive Practice Hub entry point. The page itself is static HTML so search engines and retrieval agents can read the full question list without executing JavaScript.
