Edexcel GCSE series and parallel circuit notes and worksheet

Notes and worksheet on series and parallel circuits covering voltage, current and resistance for the Edexcel 9-1 GCSE. There’s a version filled in for revision and a blank worksheet for students to fill in themselves.

The notes aim to put all on one page all the rules of potential difference, current and resistance for series and parallel circuits, something students have a lot of trouble managing. In particular, it shows the way that the rules of series and parallel circuits for current and PD are opposite to one another, something also stressed in a “how do I remember all this?” guide at the bottom. A power triangle for Ohm’s law is also included to help students know what calculation to do.

These notes should be suitable also for teaching OCR Gateway GCSE physics. Please note that this set of notes isn’t needed for Edexcel international GCSE which doesn’t go as far into the topic.
