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 scientific fields?Solid-state physics, materials science, electrical engineering, and electromagnetism
2. How do dielectrics help in a capacitor?In a capacitor, a dielectric sits between the two metal plates. It can store electrical energy by aligning tiny electric dipoles, making the capacitor hold more charge in a small space.
3. Why are dielectrics important for everyday electronics?They keep electricity from leaking out of wires and components, protect us from shocks, and let tiny parts fit close together in devices like phones and computers.

Dielectric Constant (εr): Ratio of the capacitance of a capacitor with the material to one with vacuum; indicates polarization strength.
Dielectric Loss: The dissipation of energy as heat when an alternating electric field is applied to a dielectric.
Electrical Breakdown: The irreversible loss of insulating properties in a dielectric material under excessive electric field stress.
