Скачать или смотреть GCSE Physics Practical: Investigating Resistance & Wire Length | Philip Harris

📏 Does the length of a wire affect its resistance?
In this GCSE Physics required practical, we demonstrate how to measure how resistance changes with wire length — giving students hands-on experience with key concepts in electricity and circuit behaviour.

⚡ In this video, you’ll learn how to:
✔️ Set up a simple circuit with a wire of varying lengths
✔️ Measure current and potential difference using a multimeter or voltmeter/ammeter
✔️ Calculate resistance using Ohm’s Law
✔️ Record data and analyse trends in a results table and graph

✅ Designed for AQA, Edexcel, and OCR GCSE Physics specifications.

🎓 Perfect for physics teachers, science technicians, and students revising for required practical exams.
