Static Electricity vs Human-Harnessed Electricity

What will create static electricity?

• Rubbing a plastic comb on a piece of wool.

• Flipping on a light switch in the classroom.

• Allowing like forces to attract (negative attracts a negative).

• Wrapping a wire around an iron and sending a charge through a wire.

What is the definition of static electricity?

• The tiny particles called atoms are the basic building blocks of all matter

• A complete path around which electricity can flow.

• The buildup of an electricalcharge on the surface of an object. It's called this because the charges remain in one area rather than moving or "flowing" to another area.

• Electricity that is brought under control by people.

Which of the following correctly describes one way in which static electricity is different from the current electricity that is used in homes?

• Static electricity is a quick release of energy.

• Static electricity requires magnets and coils of wire.

• Static electricity flows at a constant rate.

• Static electricity always goes in the same direction.

Why is current electricity a better source for use in our homes than static electricity?

• Electricity is used where people live.

• Materials must be used to create electricity.

• A steady flow of electric current is needed in our homes.

• Different amounts of electricity are used at different times

• During the spring when the ground is wet
