Atoms
True or False: You can see atoms with a regular microscope.
False
What allow electrical charges to flow through them easily?
Conductors
Static electricity
Open or closed circuit: The light bulb is on.
Closed
Neutrons have what charge?
Neutral, no charge
What don't allow electrical charges to flow through them?
Insulators
Electrons are pulled towards this pole (positive or negative) of a battery.
Positive
Besides a wire or conductor, a switch, and the thing it is powering (like a light bulb), all circuits need this.
A battery or other type of power source
Protons have what charge?
Positive
What allow a small amount of electrical charge to flow through them?
Resistors or semiconductors
Electrons are pushed away from this pole (positive or negative) of a battery.
Negative
This type of circuit has only one pathway for electricity to flow.
Series circuit
Electrons have what charge?
Negative
Insulator or Conductor: Gold
Conductor
When electrical currents flow through a circuit in only one direction. Hint: This type of current is in battery-powered devices.
Direct Current (DC)
This type of circuit has multiple pathways for electricity to flow.
Parallel circuit
What two subatomic particles are found in the nucleus of an atom?
Protons and neutrons
Insulator
When electrical currents flow through a circuit changing directions every second. Hint: This type of current is common in buildings.
Alternating Current (AC)
True or False: Many circuits have resistors so that the flow of electrical energy won't be too powerful.
True
