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 related topics?Smart grids, renewable energy integration, grid modernization, energy storage, and cybersecurity
2. Why do power lines use different voltages?High voltages carry electricity far with less loss, then transformers lower the voltage so it is safe for everyday use.
3. How did alternating current (AC) become the main way to send electricity?AC lets transformers change voltage easily, so it can travel long distances and then be stepped down for homes, which made it more efficient than old direct current systems.

Transmission Lines: High-voltage power lines that carry electricity over long distances from power plants to substations.
Distribution Lines: Lower-voltage power lines that carry electricity from substations to individual consumers.
Smart Grid: An modernized electrical grid that uses digital technology to improve efficiency, reliability, and sustainability.
