Electrical properties of materials

The term "electrical property" refers to the behavior of a material in a specific electrical condition. Whenever electrical current flows in a material, the behavior of the material indicates the electrical properties. The electrical properties vary with respect to different types of materials. Some engineering materials have a better electrical property in comparison to others.
