If wrong: That is not correct. There is not a Southern Interconnection.

Q: The United States has brand new and only completely up-to-date equipment on its power grid.
- True
- False
A: False
If right: Correct. Unfortunately, the United States does not have a new power grid. However, the U.S. is currently working to replace its old power grid with newer more up-to-date equipment, and will implement the smart grid technology already in use in other countries.
If wrong: Incorrect. Unfortunately, the United States does not have a new power grid. However, the U.S. is currently working to replace its old power grid with newer more up-to-date equipment, and will implement the smart grid technology already in use in other countries.

Q: The electric grid was set up in 1926 because of the Electricity Supply Act.
- True
- False
A: True
If right: Good!
If wrong: Incorrect. The National Electric Grid was set up in 1926 with the Electricity Supply Act.

Q: The energy sector is described as providing an enabling function across all the critical infrastructure sectors.
- True
- False
A: True
If right: Correct!
If wrong: Incorrect. This is true, energy enables all the critical infrastructure sectors.

Q: The current power grid in place in the US has no storage capabilites, meaning that those collecting solar or wind energy cannot readily sell it and provide it directly to the power grid.
- True
- False
A: True
If right: Correct.
If wrong: This is true. One of the benfits to implementing a nation-wide smart grid system will be adding storage capacity in which energy can be stored.

Q: Electrical grids cropped up across the United States during what time frame?
- The late 1800s
- The late 1900s
- The late 1700s
A: The late 1800s
If right: Great! This is correct, both AC and DC power grids sprang up around the United States. They began in competition of each other but in the 1900s governments began creating regulations and regulatory groups.
If wrong: No, the correct answer is the late 1800s. Both AC and DC power grids sprang up around the United States. They began in competition of each other but in the 1900s governments began creating regulations and regulatory groups.

Q: A ________________________ is a sophisticated monitoring device that can help give operators almost real-time information of what is happening on the electrical grid.
- multi-phase monitor
- synchrophasor
- grid flux monitor
A: synchrophasor
If right: That is great!
If wrong: No, that is not correct. The correct answer is "synchrophasor".

Q: The name of the act that Congress passed in 2007 that provided support for work on development of the smart grid system is __________________________________.
- Energy Independence and Security Act (EISA)
- Power Improvement Act (PIA)
- Grid Improvement and Energy Act (GIE)
A: Energy Independence and Security Act (EISA)
If right: That is great! The full name stated in your reading was, " Title XII of the Energy Independence and Security Act of 2007" the act is also known as EISA.
If wrong: No, the correct answer is: the Energy Independence and Security Act of 2007. The full name stated in your reading was, " Title XII of the Energy Independence and Security Act of 2007" the act is also known as EISA.

Q: Alternating current is used on the power grid in the United States because _______________________________________________________ .

- it is cheaper to produce
- it causes less electronic interference
- it flows faster than direct current
A: it is easily manipulated to the correct voltages
If right: That is absolutely correct! Very good!
If wrong: The correct answer is: "it is easily manipulated to the correct voltages"

Q: The United States has a critical dependence on energy.
- True
- False
