Understanding electricity is a vital part of GCSE Physics. This page includes all my free GCSE Electricity video lessons, practice questions, and answers to help you develop a clear understanding of electrical circuits and calculations.
You’ll find lessons covering current, potential difference (voltage), resistance, charge, power, and energy, as well as series and parallel circuits, circuit symbols, and required practicals. Each video and worksheet is aligned with the AQA, OCR, and Edexcel GCSE and IGCSE Physics specifications.
You can also explore related topics such as Energy and Waves to see how electrical energy transfers and wave behaviour connect to this topic.
Watch my free GCSE Physics Electricity videos below. Each lesson explains a key concept with worked examples, circuit diagrams, and exam-style questions to help you understand both the theory and the maths involved in electrical circuits.
Test your knowledge with these GCSE Electricity practice questions that accompany the videos. They are designed for AQA, OCR, and Edexcel GCSE Physics students, and will help you apply what you’ve learned to real exam-style problems.
You’ll find questions on Ohm’s Law, charge flow, current–voltage graphs, and electrical power and energy.
Check your answers here. Each question includes a fully worked solution and step-by-step explanation so you can understand where each formula comes from and how to use it correctly. These detailed answers will help you develop confidence in tackling both calculation and explanation questions on electricity..
In this video I take a look at the equations that involve charge, current, potential difference, resistance and power.
The UK mains is 230V and domestic plugs are protected by fuses. The earth wire is also an important safety feature for many appliances. In this video we look at how these things work.
Here is a quick video demonstrating how to wire a plug.
More videos and questions on electricity will be coming soon
