Electricity Review

When electricity travels in a path, this path is called a...

• circuit

• pathway

• outlet

• battery

What part of an electrical circuit is used to open and close the circuit?

• filament

• switch

• bulb

• battery

True or False: Electricity can NOT flow easily through conductors.

• True

• False

Does a circuit have to be open or closed in order to for electricity to flow through it.

• OPEN

• CLOSED

What is ELECTRICITY?

• The flow of the sun's energy.

• The flow of positive charges (protons)

• The flow of negative charges (electrons)

• The flow of energy from lightbulbs

What happens when you have an OPEN circuit?

• You have a complete path and the lightbulb will work.

• You have a break in the path and the lightbulb will not work.

• You have only one path and the lightbulb will work.

• You have more than one path and the lightbulb will not work.

Why won't this circuit work?

• There isn't any battery.

• It needs another lightbulb.

• It has a break in the path

• It needs a switch

Which allows electrons to flow through it?

• insulator

• conductor

• engineer

• resistor

Which is an example of an insulator or resistor?

• paper clip

• blanket

• coin

• nail

Which is an example of a conductor?

• fork

• pencil

• paper

• shoebox
