|
Static Electricity
|
A single electrical charge that doesn't move.
|
|
|
Electric Charge
|
A form of energy we use to power devices
|
|
|
Ground Fault Circuit Interruptor (GFCI)
|
An outlet that monitors electric current and detects ground faults. It interrupts power almost instantaneously to prevent electrocution.
|
|
|
Charge
|
A quality of electricity that can be positive or negative, similar charges repel each other and opposite charges attract each other.
|
|
|
Conductor
|
An object or material that allows an electric current to travel easily through it.
|
|
|
Insulator
|
An object or material that will not allow an electric current to travel through it.
|
|
|
Fuse
|
A thin wire placed in a circuit to prevent too much electricity from travelling through the circuit.
|
|
|
Power Source
|
This is what creates the electricity. (Battery, generator, solar panel)
|
|
|
Load
|
The device that uses electricity.
|
|
|
Closed Circuit
|
A complete circuit through which electricity flows.
|
|
|
Open Circuit
|
A circuit which has a break in the loop and so electricity cannot travel through it.
|
|
|
Current Electricity
|
The steady flow of electrons through a conductor between objects or places.
|
|
|
Parallel Circuit
|
A circuit in which a current travels along two or more separate paths to different devices. The current travels through each part of the circuit at the same time.
|
|
|
Series Circuit
|
A circuit in which the current travels along a single path to two or more electric devices. The current travels through each port of the circuit in turn.
|
|
|
Switch
|
A device that controls the flow of electricity.
|
|
|
Power Plant
|
Place that generates electricity for communities.
|
|
|
Transformer
|
Steps voltage up for transmission over distribution lines.
|
|
|
Substation
|
Buildings that contain transformers that step down high voltage to low voltage electricity for use in homes and buildings.
|
|
|
Distribution Lines
|
Carries electricity to houses and buildings. Transformer on pole steps down voltage before entering house.
|
|
|
Ampere (A)
|
A unit of electric CURRENT
|
|
|
watt (W)
|
Unit of electric POWER
|
|
|
Volt (V)
|
the electric potential. The energy source pushes electricity through a circuit. This push is called Voltage and is similar to water pressure in a garden hose.
|
|
|
kiloWatthour
|
Equal to the energy of 1000 watts working for 1 hour.
|
