electron
Positive and negative electric charges that are separated from each other and are not moving
static electricity
A small particle in the nucleus of the atom with a positive charge
proton
The material in a lightbulb (usually thin wire) that makes light when heated by an electric current
filament
A small particle in the nucleus of the atom with no electrical charge
neutron
A material that prevents the flow of electricity (plastic, rubber, glass, or air)
insulator
A substance (usually metal) through which electricity will flow (copper and aluminum are common)
conductors
