AQA GCSE Physics Electrical Power P = I²R Calculations Visual Revision Guide | EVERY Method Teaching Slides
AQA GCSE Physics electrical power P = I²R calculations presentation. EVERY method, worked examples, transmission and resistor questions. AQA 4.2 H.
P = I²R is the AQA Higher tier power equation that explains why electricity is transmitted at high voltage and low current, and exam questions test exactly that reasoning. This presentation drills the equation alongside the conceptual link to national-grid transformers, so learners can both calculate the power dissipated and explain why low-current transmission reduces it.
What's inside:
- Lesson-ready slides on P = I²R derivation, applications, and rearranging
- Worked examples on power dissipated in resistors, transmission lines, and domestic wiring
- A national-grid transmission sequence: step-up transformer, low current, P = I²R loss reduced, step-down transformer
- Guided practice and exam-style problems on Paper 2 contexts
- EVERY method scaffolding on every example slide
AQA specification reference: 4.2 Electricity, section 4.2.1 (current, p.d. and resistance) and 4.7.3 (transformers and the national grid for Higher Triple). Higher tier focus.
Who it's for: AQA GCSE Physics teachers, Higher tier intervention leads, GCSE tutors targeting Grade 7-9 progression, parents supporting Year 11 learners through final revision, and homeschool families on the UK national curriculum.
