Facts About Phin
100
This is an example of a closed circuit. In this example, are electrons flowing in a continuous loop?
Yes, a closed circuit allows for the continuous flow of electrons through the system.

This kind of circuit issue occurs when the circuit is not connected in a continuous loop. This can happen on purpose, like when someone uses a switch, or not on purpose, like when a tree falls and snaps a powerline in half.

Electrons are small particles that travel through wires to produce electricity. They are able to produce electricity because of their charge. Are electrons:
A. Positively Charged
B. Negatively Charged
C. Neutrally Charged
B. Negatively Charged

This kind of circuit issue occurs when something falls on a powerline and creates a path for the electrons to flow out of the wire, through the object, and into the ground.
Grounded Circuit

Which energy source was the most heavily relied upon in Texas in 2020 and 2021?
Natural Gas

Phin was born in what year?
2001
300
What material is used in a circuit to conduct electricity, allowing electrons to move through the system?
Metal
300
This kind of circuit issue occurs when something touches a powerline and creates a path for the electrons to flow from the wire, through the object, and into the air.

Is Phin the oldest, youngest, or middle sibling in his family?
Oldest

What material is commonly used to insulate a circuit, protecting wires from losing electrons to the surroundings.
Rubber / Plastic

A tree falls on a powerline connected to Jim's house. The power is still working in all of Jim's neighbors' houses. Did the tree cause a broken circuit or a grounded circuit?
Broken Circuit

A new solar energy farm is deciding whether or not they want to build their powerlines underground or above ground. Give me one reason they should build their powerlines underground, and one constraint they might when doing so.
Reasons: Protection from broken/grounded/short circuits.
Constraints: Expensive, harder to maintain, doesn't protect from floods/earthquakes

Phin played what sport in high school? Hint: It is NOT a sport offered at Chief Leschi
Tennis

In the electrical circuit of a house, there are three separate wires that enter and exit the building. What are the functions of these three wires?
Hot wire takes electrons into the building to the outlets. Neutral wire takes electrons from the outlets out of the building. Grounding wire will take excess electrons out of the circuit and into the ground as a safety measure.

A homeowner plugs in a toaster and it immediately shuts off power to all of the kitchen outlets. What feature of a home's electrical circuit may have caused the circuit to automatically open and stop the flow of electrons?
The Circuit Breaker
