GCSE Physics - Electric Fields - Field Lines | Ionisation of Air (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Electric Fields and Field Lines How to draw electric field lines for isolated positive and negative charges. The rules for drawing field lines, including the direction of arrows and leaving the surface at a right angle. 2. Electric Field Strength How the strength of an electric field changes with distance from a charged particle. 3. Electrostatic Forces Electrostatic attraction between oppositely charged particles. Electrostatic repulsion between particles with the same charge. How to draw the combined electric field for interacting particles. 4. Ionisation of Air How a strong electric field can cause air particles to lose electrons (ionisation). Explanation of how ionised air can conduct electricity, leading to sparks. ** EXAM BOARD SPECIFIC INFO ** AQA - Only triple science (both foundation and higher tier) IGCSE Edexcel - Only triple science (and only higher tier) Edexcel - Only triple science (both foundation and higher tier) OCR 21st Century - Only triple science (both foundation and higher tier) OCR Gateway - Only triple science (both foundation and higher tier) ** CHAPTERS ** 0:00 What are Electric Fields? 0:21 How to Draw Electric Field Lines 1:06 Understanding Electric Field Strength 1:21 Electrostatic Attraction and Repulsion Explained 2:03 How Electric Fields Ionise Air ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • KS3 Physics      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel
