Which answer avoids the common misconception in this topic? Context: wind-turbine generator boundary. Learning objective: (Physics only) (HT only) Explain how the ratio of potential differences across the two coils depends on the ratio of turns on each coil.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): wind-turbine generator boundary shows (Physics only) (HT only) Explain how the ratio of potential differences across the two coils depends on the ratio of turns on each coil. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): wind-turbine generator boundary shows (Physics only) (HT only) Explain how the ratio of potential differences across the two coils depends on the ratio of turns on each coil. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Transformers (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The wind-turbine generator boundary detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
