Electricity and electronics - circuits

Students should be familiar with Ohm’s Law and the basic consequences of Kirchoff’s laws from GCSE. They are unlikely to have covered capacitors, but will have seen the basic characteristics of semiconductor devices.


The collection consists of videos giving background videos for for Ohm’s Law, capacitors and semiconductors as well as circuit simulations from PhET to use alongside worksheets to allow students to take measurements. There are also some relevant IOP resources from the Teaching Advanced Physics to help teachers with background as well as further teaching ideas.

Resources cover the specification points:

  • using mathematical methods to calculate values in electronic circuits, including:

    • current and voltage, using Ohm’s law

    • resistance and capacitance, where components are in series and parallel

    • electrical power

  • the junction characteristics of semiconductor devices such as diodes and transistors
