Learn how electric circuits work and how to measure current and potential difference with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

EMF vs potential difference…. my head hurts I have been asked to demonstrate some electrical things to a GCSE student. One of the things on the syllabus is potential difference, and another is EMF – ...
