1. Electricity Lesson 2 Electrical Charge Carriers

2. A. A material in which electrical charges do not move freely from place to place is called a Insulator.

3. B. Conductors- a material in which electrical charges move freely from place to place.

4. C. Examples of insulators- rubber, Saran Wrap, cotton, paper, silk, wool, nylon, glass, and wood

5. D. Examples of conductors- Brass, silver, nickel, copper, steel, aluminum, and water (if not pure)

6. E. Thick wires make better conductors than thin wires of the same material.

7. F. Short wires are better conductors than long wires of the same material.

8. G. Some materials are better conductors than others.
