Plastic, wood, glass and rubber are good electrical insulators. Examples of materials that are conductors are most metals. Reasons why wood is a good insulator: Wood works well as an insulator because there is a void (vacuum) in it. Wood is a complex material made up of many different compounds. Is lead a conductor or insulator? As a result, when a charged insulator (such as a positively charged glass rod) is brought close to the conductor, the (total) charge on the insulator exerts an electric force on the conduction electrons. This can be seen in rubber-coated wires and cables. Insulating materials include plastic, rubber, leather, glass, and ceramic. In metallic conductors such as copper or aluminum, the movable charged particles are electrons. Conductor Lead is a metal and it will conduct electricity.

Eg: paper, wood, rubber. . However, there are non-metals also that conduct electricity. Its conducting properties may be altered in useful ways by introducing impurities ("doping") into the . Going by definition of conductor, and classification of materials, lead is a conductor of both electricity and heat. Insulator. In fact, metals vary widely in their conductivity but, overall, they are better conductors of heat than most liquids and gasses. Some common. it is an insulator. A poor conductor means that the substance will not easily conduct heat or electricity (or both) as easily as a conductor. But it's not up there with copper and silver. Let's learn various uses of conductors and insulators: Uses of Conductors. Plastic is commonly referred to as an insulator, although it may absorb some heat, but not as a conductor. Insulators, on the other hand, are materials that do not allow electrons to flow freely through them. Is pencil lead an insulator? Is lead a conductor or insulator - Answers.com.
