Explanation: Branch 2: V=9V, R=6Ω. I = 9/6 = 1.5A. Have a specific question about a circuit diagram

Before calculating anything, look at the diagram. Determine if the components are lined up end-to-end (series) or split into rungs (parallel).

A hairdryer uses a current of 5 A and has a resistance of 44 Ω. Calculate the voltage needed to operate it. (Show formula, working, unit – 5 marks) I = 9/6 = 1

Words like "identical bulbs" or "negligible internal resistance" change how you solve a problem. "Identical" means you can split voltage or resistance evenly.

Know the colors and functions of the Live (Brown), Neutral (Blue), and Earth (Yellow/Green) wires.

A) Current B) Potential difference C) Resistance D) Power

F2 science often explores how we use electricity safely at home. These exercises focus on practical applications.
