Electricity
How people use electricity.
Almost every person in the world uses electricity for things like,
Refrigerators
Lights
Computers
TV's
Radios
and Microwaves
Electricity is very important in our lives today.
Who invented electricity?
There were several people credited with the
invention of electricity including William Gilbert,
and Benjamin Franklin. Benjamin Franklin did
a kite experiment and William Gilbert did a
science experiment.
Microwaves
Thanks for watching!!!!!!
To heat our food microwaves
must be powered by
electricity. Electricity is
transferred into the microwave through a socket plug. Inside a microwave is a generator called a magnetron. The magnetron converts electricity to high powered radio waves, that heat our food. The magnetron then blasts the waves into the food compartment. There is also a turning trey to heat the food evenly. The radio waves bounce off the metal walls and heat the food.

Outlets
People use outlets everyday to
power things like radios, TV's,
toasters, vacuums, and lamps.
But for people to use these
objects electric wires have to
travel through the walls from
the electric panels to the outlet
so we can get electricity. For this to happen the hot wire or main wire brings electricity to the outlet while a second wire the neutral wire returns power
from the outlet back to the panel.

LED lights
People today are starting to use
LED lights. LED's are the new version
of the lightbulb. LED stands for light
emitting diode. They do not have
have a gas or filament inside them
as the old lightbulbs did. A filament
is a conducting wire or thread with a
high melting point. LED's have a life
span of 50,000 hours of reliable light. If we didn't have electricity we could not power all of the electronics and everyday items that people all around the world use.
