On the specification
| Board | Spec | Statement |
|---|---|---|
| AQA GCSE 8463 | 4.7.3.4 | Transformers |
| Edexcel GCSE 1PH0 | 13.5 | Explain how an alternating current in one circuit can induce a current in another circuit in a transformer |
| Edexcel GCSE 1PH0 | 13.6 | Recall that a transformer can change the size of an alternating voltage |
| Edexcel GCSE 1PH0 | 13.7P | Use the turns ratio equation for transformers to calculate either the missing voltage or the missing number of turns: coil ondary sec turns number coil primary turns number coil ondary sec across difference potential coil primary across difference potential |
| OCR GCSE J249 | P4.2g | Explain how the effect of an alternating current in one circuit, in inducing a current in another, is used in transformers |
| OCR GCSE J249 | P4.2h | Explain how the ratio of the potential differences across the two coils in a transformer depends on the ratio of the numbers of turns in each |
| OCR GCSE J249 | P4.2i | Apply the equations linking the potential differences and numbers of turns in the two coils of a transformer |
| OCR GCSE J249 | PM4.2ii | Apply: potential difference across secondary coil(V) potential difference across primary coil(V) |
