Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the discipline?A subfield of electrical engineering focused on electric power
2. What is the primary focus?Generation, transmission, distribution, and utilization of electric power
3. What is power engineering and why is it important?Power engineering is the science that makes sure electricity travels safely from power plants to our homes. It keeps lights, computers, and many other things working.
4. How do power engineers send electricity over long distances?They use big power lines that carry alternating current (AC) because AC is efficient for long trips. For very long distances, they sometimes use special direct current (DC) lines that lose less energy.

Generation: The process of converting primary energy sources into electrical energy.
Transmission: The bulk transfer of electrical energy over long distances at high voltages.
Distribution: The delivery of electrical energy from the transmission system to end-users.
AC Power: Alternating Current, where the direction of electric charge flow reverses periodically.
