How to Solve Ohm's Law Explanation Questions: Edexcel iGCSE Physics (4PH1)

Electricity questions where you have to explain how current changes when resistance changes; voltage changes when current changes (for a fixed resistor) → how voltage on another component changes (usually a resistance-changing component) I hope these steps help you solve these repeated questions and gain full marks! 00:00:00 Intro to Question Types 00:02:56 Parallel and Series Interconversion 00:10:08 Fixed Resistor and Resistance-Changing Component 00:20:42 ALL QUESTIONS IN PAST PAPERS CATEGORIZED 00:21:06 PRACTICE!!! #physics #igcse #edexcel #pearson #gcse #gcsephysics
