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) Identify np and ns as the number of turns on the primary and secondary coils?
Direct answer
In Physics, this page helps you answer questions about (Physics only) (HT only) Identify np and ns as the number of turns on the primary and secondary coils 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) voltage-change cue 183 and Transformers (HT only) force-link cue 184.
Key terms
- Transformers (HT only) voltage-change cue 183: A iron-filings field pattern prediction cue for (Physics only) (HT only) Identify np and ns as the number of turns on the primary and secondary coils.. 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 primary and secondary...: Instead, identify the exact Unit 4.7 idea in Transformers (HT only), then explain how it links to a student comparing motor and generator effects and the objective to identify np and ns as the number of turns on the primary and secondary coils.
