My daughters school have phoned today, they are 'doing' electricity in 2 weeks, they want me to do some 'maths & electricity' with the kids.
Problem is they are 4+
Now I have thought of measuring resistence of equal x section and varying lengths
And equal lengths and varying x sections
Has anyone got any other ideas.
Didn't think i would end up 'teaching' again
