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!
