Transformers (HT only): primary-secondary coil comparison application shows (Physics only) (HT only) Identify transformer power input and output in watts. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): primary-secondary coil comparison application shows (Physics only) (HT only) Identify transformer power input and output in watts. 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 primary-secondary coil comparison application detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
