What the syllabus asks
- determine the electric potential energy stored in a capacitor from the area under the potential–charge graph
- recall and use W = 1/2QV = 1/2CV2
How hard the questions are
- Recall0
- Apply5
- Analyse6
- Not banded0
Derived from the command word Cambridge prints in each question, banded by a fixed table beside the syllabus's own definitions. A question printing no command word is unbanded: unknown, not middling.
