A bulb
A system that uses electrical energy to generate light and heat energy.
Circuit
Not complete or partial path through which an electrical current may flow
Current electricity
The continuous flow of electrons through a conductor
Dry cell
Commonly known as the battery, this uses chemicals to make an electrical charge.
Electricity
A form of energy which can be transferred from one place to another in a closed circuit.
Energy
The ability to do work; various forms exist such as heat, electricity, chemical and light energy.
Filament
Resistant wire in a bulb which transforms electrical energy into light energy.
Insulator
A material that does not easily conduct electricity (a nonconductor).
Schematic
A diagram showing how something is put together, for example a wiring diagram
Static

Switch
A device in an electrical circuit that opens and closes the circuit.
Symbol
A wrirren sign that represents a part of an electrical circuit in a schematic.
