What is an electrical circuit?

• A robot that moves electrons from one end to another.

• When the electrons change forms.

• A closed path for electrons to flow through.

• A tiny racetrack in which neutrons go around in a circle.

The pole on top of the bumper car helps it move by _

• Operating a giant turbine and using air flow to propel the car forward.

• Completing an electrical circuit to do mechanical work.

• Picking up electrical signals circulation in the air.

• Connecting to a track that holds the car upright.

From Friday's Lesson: What is Faraday's law?

• A law that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force.

• A law that describes how electrons work.

• A law that describes how circuits work.

• I really don't remember, that was like 3 days ago Ms. Gomez.

What type of materials make the best conductors?

• Woods

• Plastics

• Stones

• Metals

Watts are the combination of

• pressure and flow

• pounds and meters

• volts and amps

• electrons and neutrons

What is a major practical purpose of dams?

• They are so pretty.

• They can generate electricity.

• They create lakes for us to swim in.

• They catch fish to feed the community.

What is the difference between AC and DC currents?

• AC currents alternate flow direction and DC currents do not.

• AC current is more affordable than DC current.

• DC current only works in Washington DC.

• AC current only works in hot, dry climates.

Photovoltaic Power (PV) derives its power from

• Gravity

• Water

• a battery

• the sun

Plugs with a ground prong are typically used for electronics that require more power, such as laptops, PCs, vacuums, and power tools. Why do you think some plugs have a third prong?

• Because it just looks better.

• If damage or a malfunction occurs, altering the circuit, the ground wire is an emergency path that protects you and your devices from electric shock.

• the third prong helps hold the plug in the wall.

• the third prong sucks more electricity out of the outlet.
