Electricity
|
A form of energy produced by the movement of electrons.
|
Electron
|
The negatively charged part of an atom.
|
Static Electricity
|
The build-up of electrical charges on top of material. It is called "static" because there is no current flowing, as there is in alternating current (AC) or direct current (DC).
|
D-cell
|
Source of electricity in the light bulb experiment.
|
Battery
|
More than one cell
|
Electricity source
|
Provides the energy to light the bulb.
|
Electricity Receiver
|
A component that uses the electricity from the source to make something happen (for example, to light the bulb).
|
Circuit
|
A pathway for the flow of electricity.
|
Filament
|
The part of a light bulb that gets hot and makes light.
|
Component
|
One part of a circuit system- D-cell, bulb, switch, motor or wires.
|
Fahnstock Clip
|
Metal clip that connects wires in a circuit.
|
Switch
|
Device used to open and close circuits.
|
Open Circuit
|
An incomplete circuit through which electricity will not flow.
|
Closed Circuit
|
A complete circuit through which electricity flows.
|
Schematic diagram
|
A way to represent a circuit on a piece of paper.
