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. Who discovered Lichtenberg figure?Georg Christoph Lichtenberg in the late 18th century
2. What is the scientific classification?Branching electric discharge phenomena in dielectric materials
3. What is the key mathematical property?Exhibits fractal geometry, characterized by self-similarity
4. What are Lichtenberg figures?They are branching patterns made when a high electric field breaks through an insulating material, leaving a lightning‑like design on the surface or inside the material.
5. Why do Lichtenberg figures look like lightning?The electric discharge travels along paths that are the easiest to follow, creating branching shapes that resemble the way lightning splits into many branches.

Dielectric Strength: The maximum electric field a material can withstand before breaking down and conducting electricity.
Electrical Breakdown: The process where an insulating material loses its insulating properties and becomes conductive due to high voltage.
Fractal Geometry: A branch of mathematics that studies complex, self-similar patterns that repeat at different scales.
High-Voltage Engineering: The field of electrical engineering concerned with the design and operation of systems that use very high electrical potentials.
