The smallest particle of an element that has the chemical properties of the element. Can exist either alone or in combination with others.
What is an atom?
100
A form of energy created by the free or controlled movement of charged particles such as electrons.
What is electricity?
100
Emitting light after being heated to a high temperature.
What is incandescent?
100
A circuit where two or more components are connected side by side, and there is more than one path for the current to flow.
What is parallel circuit?
100
A straight-line drawing showing the layout of an electric circuit.
What is schematic diagram?
200
An energy storage device composed of electrochemical cells.
What is a battery?
200
An elementary particle that has a negative electrical charge and travels around the nucleus of an atom.
What is an electron?
200
A material or device that prevents or reduces the transmission of heat, electricity, or sound.
What is insulator?
200
The type of charge that exists on the proton.
What is positive charge?
200
A circuit whose components are connected one after another and that has only one path for the current to flow.
What is series circuit?
300
A quantity of electricity.
What is a charge?
300
A branch of physics that deals with electronic devices and with the giving off, action, and effects of electrons in vacuums, gases, and semiconductors.
What is electronics?
300
A semiconductor that emits light when a current passes through it.
What is Light-emitting diode (LED)
300
An elementary particle located in the atomic nucleus that has a positive electric charge equal to the negative electric charge of an electron.
What is proton?
300
A device that opens and closes the connections in an electric circuit.
What is a switch?
400
A conductive path through which an electric current flows.
What is a circuit?
400
Either of the two conductors through which electricity enters or leaves something, such as a battery or a piece of electric equipment.
What is an electrode?
400
The type of charge associated with electrons.
What is negative charge?
400
Force working against the flow of electricity.
What is resistance?
400
A conductor attached at the point where electricity enters or leaves a circuit, such as on a battery.
What is a terminal?
500
A material capable of transmitting energy, particularly in the forms of heat and electricity.
What is a conductor?
500
A thin wire that, when an electric current passes through it, acts as the light-producing element of an incandescent bulb or the electron-emitting element in a vacuum tube.
What is a filament?
500
The positively charged central portion of an atom; contains nearly all of the atomic mass.
What is nucleus?
500
A component of an electric circuit that resists the flow of electricity and is used to control the flow of electric current.
What is resistor?
500
A strand of metal, usually copper, used to conduct an electric current with very low resistance.
