What is electricity?

• is a phenomenon created by the movement of electrons from one atom to another

• The unit of measure for resistance

• A common return path for electric current, or a direct physical connection to the Earth

• the physical medium that connects the nodes: ethernet cable, USB cable, coaxial cable

What are the different types of electricity?

• AC

• DC

• electron

• protron

What does "cyber" mean?

• means "to steer" or "to navigate."

• means "flow" or "outerspace"

• means "to view" or "to maneuver."

• means "to maintain" or "to program."

What is true about a parallel circuit?

• If one component is removed, the circuit will not break.

• It will only work with DC current.

• The same current flows through all the components.

• the device works like a pinwheel, steam spins the blades

Which circuit is connected in parallel?

• 
• 

What is true about a series circuit?

• If one component is removed, the circuit will not break.

• It will only work with DC current.

• The same current flows through all the components.

• the device works like a pinwheel, steam spins the blades

Which circuit is connected in series?

• 
• 

______creates a domain for human operations that is not limited by a physical environment

• Cyberspace

• The study of Humanities

• The study of Liberal Arts

What happens if you add one more LED in series?

• The LEDs become dimmer since you add more resistance.

• The LEDs become dimmer since you add more current.

• The LEDs become brighter since you reduce the resistance.

• The LEDs become brighter since you add more voltage.

What is an Ampere?

• a unit of electric current equal to a flow of one coulomb per second

• a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to

  that of an electron, but of opposite sign

• Dissimilar metal electrodes contained within an electrolyte.

• Wires used to carry electricity over thousands of miles.
