This is a fully-resourced revision lesson which covers the content detailed in the CORE & SUPPLEMENT sections of topics P5 & P6 (Electrical quantities and electric circuits) of the CIE IGCSE Combined Science 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 to 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 charge, potential difference and power
- Recall that an ammeter is connected in series
- Calculate the currents, potential differences and resistances in series and parallel circuits
- Know the safety function of the fuse
- Understand that like charges repel and unlike charges attract
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
