100
A form of energy produced by the movement of electrons
What is Electricity
100
A substance through which electrical charges can easily flow. Conduction happens when an electric current passes between two points that are physically connected. Some examples of good conductors are: wool, salt water, metals.
What is Conductor
100
A steady flow of electric charges through matter.
What is electric current
100
A machine that produces electrical current by spinning a magnet inside a coil of wire.
What is a generator
100
A brilliant electric spark discharge in the atmosphere
What is lightning
200
The negatively charged part of an atom
What is an electron
200
A material through which electric charges cannot move. Some examples of good insulators are: rubber, wool, and glass, plastic, and dry air.
What is a insulator
200
The buildup or imbalance of the same charges. Static electricity is at rest until discharged.
What is static electricity
200
A machine that produces electrical current by spinning a magnet inside a coil of wire.
What is a generator
200
Transfers of energy as heat between two bodies
What is heat
300
The ability to do work and produce power.
What is an energy
300
A steady flow of electric charges through matter.
What is electric current
300
D-cell
What is the source of electricity in the light bulb experiment
300
Electric current that changes direction continually. There are two kinds of current: alternating current and direct current.
What is alternating current (A/C)
300
The production of electricity by water power
What is hydroelectricity
400
The unit of measurement of an electric charge.
What is a Coulomb
400
A material that resists but does not stop the flow of current (the filament wire in a light)
What is a resistor
400
Happens when an electric current passes between two points that are physically connected
What is conduction
400
A device that opens or closes a circuit. This prevents or allows a current to flow.
What is a switch
400
Voltage
What is the pressure behind the flow of electrons in a circuit
500
The pressure behind the flow of electrons in a circuit
What is voltage
500
An electrical device that provides a path for electrical current to flow
What is a circuit
500
When a material that has heat is moving from one place to another and takes the heat with it
What is advection
500
A device that changes the intensity of electric current.
What is a transformer
500
Automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit
What is a circuit breaker
