Electricity Assessment Review
2
How Electricity Works
Everything is made from Atoms. Different materials have different types of atoms.
Surrounding the Nucleus are different layers of orbital shells which act like flight paths for electrons.
3
How Electricity Works
The negative charge of the neutrons is attracted to the positive charge of the Proton.
The outer most orbital shell is known as the Valance shell and in this shell some materials will have loosely bound electrons which can float to other Atoms.
4
Visualizing atoms "passing" electrons to one another as electricity flows.

Chemical Cells
Produce voltage through Chemical Reactions.
Contain two electrodes - different pieces of metal - and electrolyte.
Stop producing voltage when the material(s) run out.
13
Solar Cells
Convert the energy in sunlight to electrical energy.
Contain a material such as silicon that absorbs light energy, knocking electrons loose so they can flow freely and produce a difference in electric potential energy.
