Quick explanation

(Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil

  • This point belongs to Induced potential, transformers and the National Grid (physics only) (HT only), especially Transformers (HT only).
  • You need to be able to (Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil.
  • The key ideas to know are potential difference, physics only, and secondary coil.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect Transformers (HT only) to exam-style questions, flashcards, and revision notes for Induced potential, transformers and the National Grid (physics only) (HT only).

Quick student answer

What should you know about (Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil?

Direct answer

In Physics, this page helps you answer questions about (Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil within Induced potential, transformers and the National Grid (physics only) (HT only). Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Transformers (HT only) comparison cue 177 and Transformers (HT only) safety cue 178.

Key terms

  • Transformers (HT only) comparison cue 177: A classroom plotting compass prediction cue for (Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil.. It helps identify the relevant magnetic field, current, transformer coil, motor effect or generator induction evidence, while keeping Transformers (HT only) distinct from neighbouring GCSE Physics ideas.

Common trap

National Grid transformer reasoning: avoid AC and DC: Instead, identify the exact Unit 4.7 idea in Transformers (HT only), then explain how it links to a moving-coil microphone investigation and the objective to state that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil.
