Electricity: Current, Resistance and Potential Difference

Complete No-Prep lesson with exam questions, tasks and answers on Current, Resistance and Potential Difference for AQA GCSE (9-1) Science / Physics. The lesson covers all of AQA GCSE Physics 4.2.1.3 and a small part of 4.2.4.2 (energy transferred = charge flow x potential difference) because this helps to explain potential difference.

• This lesson is the second in the Electricity sequence and follows on from Circuits, Current and Charge.

As a Secondary Science teacher and Deputy Headteacher for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. This high quality lesson includes explanations, different types of in-lesson assessment (all with answers) and unique exam questions.

My lessons are ideal for non-Physicists - as a Biologist who retrained as a Physics teacher I know how to take learners on a journey that builds up their understanding step by step, while still going into a lot of depth. The preview video shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy.

What’s Included:
• Starter / Do Now Activity
• Explanation slides in “chunked” sections with animated diagrams.
• Worked examples of calculations / questions.
• Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “learning check / quick questions” followed by a set of in-depth questions on the learning from that “chunk” of the lesson. All questions have answers.
• Exam-style questions on the whole lesson at the end of the lesson- these are unique, based on real exam questions but not just copied from exam boards.
• Answers for all questions
• All easily editable to adapt to your teaching or to use in existing lessons.
• Slightly humorous, at points, if you like that sort of thing.

Learning objectives:

• Explain what potential difference is and how we measure it.
• Apply the equation energy transferred = charge flow x potential difference to describe how potential difference relates to energy transfer.
• Explain what resistance is, what causes it and how we measure it.
• Describe how the current through a component depends on both resistance and potential difference, and that a greater resistance will result in a smaller current for any given potential difference.
• Apply the equation potential difference = current x resistance.

The lesson was written for AQA GCSE Science / Physics but is very likely to be applicable to other exam specifications.
