Electricity and circuits REVISION (Edexcel GCSE Physics)

This is a fully-resourced revision lesson which covers the content detailed in topic 10 (electricity and circuits) of the Pearson Edexcel GCSE Physics specification. The engaging PowerPoint and accompanying resources contain a wide range of activities which include exam-style questions with clearly explained answers, differentiated tasks and quiz competitions to allow students to assess their understanding and ultimately recognise those areas which need further consideration.

The following specification points have been given particular attention in this lesson:

• The electrical symbols that represent the electrical components
• Describe the differences between series and parallel circuits
• Recall that a voltmeter is connected in parallel
• One volt is equal to one joule per coulomb
• Recall and use the equations that calculate energy transferred, charge, potential difference, power and electrical power
• Recall that an ammeter is connected in series
• Calculate the currents, potential differences and resistances in series and parallel circuits
• Explain how current varies with potential difference in resistors
• Know the functions of the wires in a plug and the safety features

This lesson has been designed to fall in line with the heavy mathematical content of the Physics specification with a number of calculation tasks and students are guided through the range of skills that they will have to employ
