Secondary revision · Physics Form 3
Current Electricity
This topic includes electric charge, current, potential difference, circuit construction, Ohm's law, electric energy, power, and safety. Learners will build circuits, measure voltage and current, calculate resistance, and explore factors affecting resistance. It directly supports ECZ exam preparation and CBC competencies, enabling Zambian students to analyse domestic circuits, understand energy consumption, and apply electrical safety principles effectively.

Outcomes
If you passGreat work! You have mastered current electricity concepts, which are fundamental for solving ECZ circuit problems and understanding electrical systems.
If you don't pass yetCurrent electricity requires careful circuit analysis. Review Ohm's law, series/parallel rules, and power calculations before trying again. Consistent practice builds confidence.
