Select the statement that would earn credit in an AQA GCSE Physics answer. Context: overhead cable transmission pole-test. Learning objective: (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current.. Which answer is most accurate for Uses of the generator effect (HT only)? Distinct revision anchor: fluxcue599a coilcue599b fieldcue599c polecue599d gridcue599e motorcue599f generatorcue599g transformercue599h compasscue599i currentcue599j voltagecue599k forcecue599l.

Uses of the generator effect (HT only): overhead cable transmission pole-test shows (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current. because magnetic effects depend on field direction, current or changing magnetic flux.

Uses of the generator effect (HT only): overhead cable transmission pole-test shows (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Uses of the generator effect (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The overhead cable transmission pole-test detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
