electric current

the flow of electricity through a conductor

battery

a source of stored chemical energy

energy

the ability to apply a force over a distance

closed circuit

a complete circuit through which electricity flows

circuit

a pathway for the flow of electricity

component

one item in a circuit

open circuit

an incomplete circuit through which electricity will not flow

contact points

the place on a component where connections are made to allow electricity to flow

conductor

a material which allows energy to pass through, particularly in the forms of heat and electricity

filament

the material in a lightbulb (usually a thin wire) that makes light when heated by an electric current

incandescent lightbulb

a device that gives off light and heat when electric current runs through a filament

static

not moving

electron

a tiny part of an atom that has a negative charge and moves around the nucleus

electric force

the force between two charged objects

semiconductor

a material that has less electric conductivity than a conductor but more than an insulator

insulator

a material that prevents the flow of electricity and heat

electromagnet

a piece of iron that becomes a temporary magnet when electricity flows through coils of insulated wire wrapped around it

electromagnetic force

a fundamental force of nature that acts between charged particles and creates electric and magnetic fields.

electromagnetism

the interaction of electric and magnetic fields

core

the material around which a coil of insulated wire is wound

motor

a device that produces motion from electricity
