Electrical Charges
Objects that have the same number of positive and negative charges
Electrically neutral
What is the flow of electrical charges through materials
electrical current
Toaster
Heat
a closed path through which electricity flows
electric circuit
Fossil fuels or uranium are used to heat up water. This produces steam. The steam moves a turbine which is connected to a generator
Thermal Power Plants
When non-metal objects are rubbed against each other, they gain or lose negative charges and become
electrically charged
Materials that allow electrical charges to move freely
example copper, silver, and metals
Conductors
Computer screen
Light
Provides electricity, with positive and negative charges
example: battery
The generator
Wind moves a turbine which is connected to a generator
Wind power plants
An object that GAINS negative charges becomes
negatively charged
Materials that do not allow electrical charges to move
example: Glass, plastic, air
Insulator
Radio
Sound
Controls the flow of electricity by closing or opening the circuit
The switch
water moves a turbine which is connected to a generator
hydroelectric power plants
an object that LOSES negative charges becomes
positively charged
Plastic covering wrapped around a copper wire
plastic wrapped around a copper wire, plastic is insulator to protect the conductor which is the copper.
Blender
Movement
Transport the electricity from the generator to the other components of the circuit-
The cables
heat or light for the sun are used to produce electricity.
solar power plants
Objects with the SAME charge _________
Objects with the OPPOSITE charge _________
Repel
Attract
Battery
Chemical
These transform the electricity into another type of energy
example: light bulbs, motors
Devices
Every socket is connected by cables to a __________
National Grid
