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 technological foundation?Essential for understanding and developing semiconductors, batteries, motors, and all electrical devices
2. Why do opposite charges attract and like charges repel?Coulomb's Law says the force between charges depends on their size and how far apart they are. Like charges push away, and opposite charges pull together.
3. How does electrical polarity help batteries work?Batteries have a positive and a negative side. The difference in polarity pushes electrons through a circuit, giving power to gadgets.

Electrical Polarity: The property of having two distinct and opposite electrical charges, positive and negative, influencing interactions and behavior.
Coulomb's Law: A fundamental law describing the electrostatic force between two charged particles, proportional to the product of their charges and inversely to the square of their distance.
Electric Dipole: A separation of positive and negative electric charges, often found in molecules, creating an electric dipole moment.
