Electricity and circuits REVISION (GCSE)

This fully-resourced revision lesson has been written to cover the major details of the electricity and circuits topic that can be assessed in the GCSE Physics and Combined Science (HT) exams. 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 points are covered in this revision 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

The main task of the lesson, which challenges the students to calculate the currents, potential differences and resistances in series and parallel circuits, is differentiated to allow students of differing abilities to access the work
