Induced potential, transformers and the National Grid (physics only) (HT only)

Question

  1. A. Induced potential (HT only): alternator output trace compass-response shows (Physics only) (HT only) Apply the principles of the generator effect in a given context. because magnetic effects depend on field direction, current or changing magnetic flux.
  2. B. It reverses the role of primary and secondary coils. (direction error).
  3. C. It assumes transformers work on direct current without changing flux. (cause error).
  4. D. It states the turns ratio changes resistance rather than voltage. (evidence error).

Answer

Induced potential (HT only): alternator output trace compass-response shows (Physics only) (HT only) Apply the principles of the generator effect in a given context. because magnetic effects depend on field direction, current or changing magnetic flux.

Explanation

Induced potential (HT only): alternator output trace compass-response shows (Physics only) (HT only) Apply the principles of the generator effect in a given context. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Induced potential (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The alternator output trace compass-response detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.

Common mistake

National Grid transformer reasoning: avoid motors and generators

Treating motors and generators as interchangeable when answering about National Grid transformer reasoning.

Instead, identify the exact Unit 4.7 idea in Induced potential (HT only), then explain how it links to a step-down transformer for a low-voltage device and the objective to apply the principles of the generator effect in a given context.
