Which answer avoids the common misconception in this topic? Context: wind-turbine generator turns-ratio. Learning objective: (Physics only) (HT only) Describe how variations in current in an electrical circuit are converted into pressure variations in sound waves.. Which answer is most accurate for Loudspeakers (physics only) (HT only)?

Loudspeakers (physics only) (HT only): wind-turbine generator turns-ratio shows (Physics only) (HT only) Describe how variations in current in an electrical circuit are converted into pressure variations in sound waves. because magnetic effects depend on field direction, current or changing magnetic flux.

Loudspeakers (physics only) (HT only): wind-turbine generator turns-ratio shows (Physics only) (HT only) Describe how variations in current in an electrical circuit are converted into pressure variations in sound waves. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Loudspeakers (physics only) (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The wind-turbine generator turns-ratio detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
