Electricity & Magnetism 2
How do we get and use electricity?
2
Poll
How do you think Clovis NM gets electricity that people can use in their homes?
Wind Energy
Coal energy
Nuclear Energy
Hydroelectric dams
3
How is electricity made?
There are many ways that depend on our geographical locations.
4
Multiple Choice
True or False: There are many different natural resources that are used to create electricity?
True
False
5
Multiple Select
Which of these is a source of energy? Choose all that apply.
Coal
Wind
Biological wastes
Water
Nuclear energy
6
Multiple Select
What does it mean to say that "electricity is less centralized"?
People commonly use a locations natural resources for energy.
Electricity is closer to the consumers.
More options exist for electricity.
Electricity is in one main location.
7
Multiple Choice
Which of these is true?
Voltage is lowered in steps for use in homes and businesses.
Homes used very high voltage electricity.
Voltage must be NOT lowered for use in common electronics.
8
Generating energy.
How does the power get made?
9
Copper wire is wound around a casing and spun around on a rotor.
Strong magnets surround the coils as the coils spin.
An electric field builds and electrons start to flow in a current.
The electrical current can be sent through conductive wires to other locations.
10
Multiple Choice
Generators are the opposite of a .....
motor
transformer
electron
power plant.
11
Multiple Choice
A generator is basically....
coils of wire turning inside a magnetic field.
magnets circling a bigger magnet.
coils of wires that have embedded magnets inside.
12
Poll
Which kind of current is used in homes.
AC - Alternating Current
DC - Direct Current
13
Multiple Select
How could you raise the amount of current made in your generator?
Add more coils of wire
Add a stronger magnetic field
Make the wire loops bigger.
Speed up the rotations of the wire.
Slow down the rotations.
14
Multiple Choice
Why do we transport power at high voltages?
So birds get shocked.
So it goes faster.
So less of the energy is wasted as heat.
15
Poll
Do household appliances use high voltage electricity?
(up to 240,000 volts)
Yes
No
NO WAY - VERY UNSAFE
Yes. Great Idea.
16
Biofuels are using a living organism or its waste to create energy.
Los Alamos is a national lab that is famous for the Manhattan Project.
I (Ms.Minteer) worked on algal biofuels for my master's degree work at ENMU.
This is popular in NM because we have an abundance of sunshine and nice days. Algae like lots of sun to grow.
