Many students offer explanations of electrical effects in terms of energy, rather than electric current
When explaining electrical effects observed in the classroom, students may opt for explanations in terms of 'energy' or the ambiguous word 'electricity', instead of referring to electric current.
The following worksheets may help to identify whether students hold this particular misconception.
For more information, see the University of York EPSE website.

The right lines approach has no place for electrical energy. Whereas energy can be stored in a cell (a chemical store of energy), it is difficult to see in what sense energy can be stored in the connecting wires of a circuit.
While the electrical circuit is clearly not a store of energy, it does provide the pathway along which energy is shifted by cell and bulb.View Resource
