On the specification
| Board | Spec | Statement |
|---|---|---|
| AQA GCSE 8463 | 4.7.3.4 | Transformers |
| Edexcel GCSE 1PH0 | 13.10 | Use the power equation (for transformers with100% efficiency): potential difference across primary coil (volt, V) × current in primary coil (ampere, A) = potential difference across secondary coil (volt, V) × current in secondary coil (ampere, |
| Edexcel GCSE 1PH0 | 13.11P | Explain the advantages of power transmission in high- voltage cables, using the equations in 10.29, 10.31, |
| OCR GCSE J249 | P8.2f | Link the potential differences and numbers of turns of a transformer to the power transfer involved; relate this to the advantages of power transmission at high voltages |
| OCR GCSE J249 | PM8.2i | Apply: potential difference across primary coil (V) × current in primary coil (A) = potential difference across secondary coil (V) × current in secondary coil (A) M1a, M1b, M1c, M1d, M2a, M3a, |
