Select the statement that would earn credit in an AQA GCSE Physics answer. Context: bench-top compass mapping evidence. Learning objective: (Physics only) (HT only) Recall and apply the transformer equation Vp / Vs = np / ns.. Which answer is most accurate for Transformers (HT only)? Distinct revision anchor: fluxcue725a coilcue725b fieldcue725c polecue725d gridcue725e motorcue725f generatorcue725g transformercue725h compasscue725i currentcue725j voltagecue725k forcecue725l.

Transformers (HT only): bench-top compass mapping evidence shows (Physics only) (HT only) Recall and apply the transformer equation Vp / Vs = np / ns. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): bench-top compass mapping evidence shows (Physics only) (HT only) Recall and apply the transformer equation Vp / Vs = np / ns. 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 bench-top compass mapping evidence detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
