Transformers (HT only): wind-turbine generator measurement shows (Physics only) (HT only) Apply the equation linking potential differences and turns to current and power transfer. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): wind-turbine generator measurement shows (Physics only) (HT only) Apply the equation linking potential differences and turns to current and power transfer. 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 measurement detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
