The batteries commonly used in school science practical work are torch batteries rated at 1.5 volt . If two of these batteries...
Thinking about voltage either in terms of size of push or in terms of a second factor (as well as the current) that sets the...
The word voltage is more approachable than the phrase potential difference so is probably enough for 11–14 year old children.
It is worth discussing energy transfer in electric circuits and linking this by analogy to other more familiar examples.
