Electrical generators – what do they do?(Challenge)



Electricity is not made by generators

Wrong Track: Electric generators make electricity.

Right Lines: Electrical generators make energy available using an electrical pathway.
Electrical generators switch power to the electrical pathway.

The charge is already in the loop: the generator sets them in motion

Thinking about the learning

The idea that electric generators make electricity is quite a common one and portrays similar thinking to the idea that electric cells provide electricity. The image here is one of the generator or the cell acting as a store of something called electricity. In fact, the cell or generator provides a potential difference that sets the charge in motion, creating an electrical pathway.
