Current, resistance and potential difference (AQA GCSE FT)

This lesson describes the relationship between current, resistance and potential difference and challenges the students to apply the equation V = I x R. The PowerPoint and accompanying resources have been designed to cover point 2.1.3 of the AQA GCSE Physics and Combined Science specifications, and are specifically written for those students who will take the foundation tier.

The lesson begins with an activity that challenges the students to work out the title of the lesson using clues to current, resistance and potential difference. The units for each of these quantities are revisited and students are reminded to scan all values in a question to check that these units are correct, or whether they need to be converted.

The main part of the lesson uses a range of exam-style questions to challenge the potential difference = current x resistance equation, and the difficulty of these questions increases, with the need to rearrange the formula in some. All answers to the questions are embedded into the PowerPoint to allow students to assess their progress.

As described above, this lesson has been written for foundation tier students and is expected to be covered in a lesson ranging between 45 minutes and an hour. It is the 4th lesson in a series of 12 lessons which have been planned to cover the main content of topic P2.
