Ellie Hurer and James Stewart explore current, resistance and potential difference. They also discuss the relationship between current and resistance in different components. Suitable for: AQA, ...
There is a current of 2.0 A in a component with a resistance of 40 Ω. Calculate the potential difference across the component.
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 – electromotive force. I had always assumed ...
