If you need help with Physics, you're in the right place. The Physics Boot Camp team has decades of experience of helping students of all abilities improve their GCSE science grades.
This course includes video lectures for every section, downloadable worksheets (with answers) for practice and a summary quiz for each section. Before you spend money on a private tutor, try our course - you can access the course when and where it suits you and the whole unit costs less than one session with a tutor!
This course covers the unit P5 - Electric Circuits, which is part of the OCR 21st Century Science Additional Science or Physics A course. If this is not your exam board or course, then check out our instructor page for a suitable course for you.
In this unit you will learn about how circuits work, how static electricity occurs and the use of electricity in the home.
We use our expertise from helping thousands of students to highlight the key areas that you need for your exam, along with helping you avoid the mistakes that everyone else makes!

Understanding the movement of electrons is essential for getting to grips with electricity and that's what you'll learn about here. Static electricity also includes the best ever physics demonstration so make sure you check out the van der graaf generator videos in the resource section
There are two types of circuit, and understanding the difference between the two will help you solve more complex circuit problems later.
Circuits don't work by magic but often students think of them in that mysterious way! This session will help you understand what is actually happening in the wires in a circuit.
Why does electricity move around the circuit in the first place? This session will help you answer that and apply your knowledge to analyse circuits.
The relationship between voltage, current and resistance is essential to understand what is happening in circuits. We've done current and voltage in the last two sessions... so guess what this one is about!
Current, voltage and resistance questions are fine in isolation but put them all together and students start losing their minds! In this session you'll learn a simple method to help you solve any circuit that the examiners throw at you.
Devices use electricity at different rates and power describes how much electrical energy they use in a certain time.
Calculating the cost of electricity used by a device is something that often causes problems on exams. Avoid those problems with this session.
Everything wastes energy and being able to calculate and write about efficiency will help you describe how.
Electromagnetic induction has a name that puts most people off. It's not as bad as it sounds - it's how electricity is generated and we'll learn how that happens in this session.
Electric motors are one of the hardest parts of this course. Put yourself ahead of the competition by learning to describe how electric motors work. Don't miss all the extra videos in the resources section.
Transformers are robots that protect us from destruction. The word also refers to electrical devices that are more likely to come up in exam questions so that's what we've concentrated on here!
