an example of an insulator is
On the other end of the spectrum, there are atoms that hold on to their electrons very tightly. A material that contains these types of atoms has very few, if any, free electrons and does not transfer electrical energy well, if at all. This type of material is called an insulator. 1 a material of such low conductivity that the flow of current through it is negligible.  insulating material, often glass or porcelain, in a unit form designed so as to support a charged conductor and electrically isolate it. The opposite of insulators, conductors have electrons that roam freely and easily transfer electrical energy to other electrons. Water is an example of a conductor. Humans, with a body composition that is 60 percent water, are excellent conduits for grounding electricity. Glass, paper, Teflon and rubber are good insulators of electricity. An insulator is a substance that allows very little electric current to flow through it. There is no perfect insulator, but materials that offer a high degree of resistance to the flow of electrons are good insulators. Full Answer >. The ability of a material to conduct electrical energy is known as its conductivity. Not surprisingly, materials that are good conductors have high conductivity, while materials that are good insulators have low conductivity. Video: Insulators and Conductors: Examples, Definitions & Qualities. In this lesson, we'll explore the reasons that some materials conduct electrical energy with ease while others block it almost completely. We'll also talk about the property of conductivity and some everyday examples of insulators and conductors. CLEP Natural Sciences: Study Guide & Test Prep / Science Courses. An insulator would be something that prevents the flow of electrical current. An example would be rubber. A conductor would be something that allows the flow of current. For …example, electrical wire (normally copper or almn) This is because the outer electrons of a conductor are not anchored like those of an insulator. Conductors tend to be metals. Some examples of insulators are plastic, glass, rubber and wood. The difference between a conductor and an insulator is that a conductor allows electrons to travel. This is because the outer electrons of a conductor are not anchored like those of an insulator. Conductors tend to be metals. <br /> Some examples of insulators are plastic, glass, rubber and wood. A material that does not easily transmit energy, such as electric current or heat. Materials such as wood, plastic, and ceramics are insulators. Fiberglass is an example of a heat insulator. (Compare conductor.) Some examples of insulators are glass, plastic and rubber. Insulators block the flow of electricity through them due to the stability of the electrons surrounding an atom. However, the electrons in some insulators, such as glass, move more freely in extremely high temperatures and can become conductors.
