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) Explain how the ratio of potential differences across the two coils depends on the ratio of turns on each coil?
Direct answer
In Physics, this page helps you answer questions about (Physics only) (HT only) Explain how the ratio of potential differences across the two coils depends on the ratio 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) pole-test cue 189 and Transformers (HT only) load-effect cue 190.
Key terms
- Transformers (HT only) pole-test cue 189: A moving-wire motor effect prediction cue for (Physics only) (HT only) Explain how the ratio of potential differences across the two coils depends on the ratio 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 steel core electromagnet demonstration and the objective to explain how the ratio of potential differences across the two coils depends on the ratio of turns on each coil.
