Conductors are materials that allow the flow of electric current, whereas insulators do not. While conductors and insulators are different in that respect, their similarity is in their makeup of atoms. It is these atoms that either have room to float around to facilitate conduction or have little fr
Examples of conductors include the human body, metals, aqueous solutions of salt, graphite, copper, silver and gold. Conductors are materials that can transfer heat and transmit electricity. Conductors have a high density, allowing particles to flow freely and collide.
The best conductor of heat is diamond with a thermal conductivity of more than 2,000 watts per meter per degree Kelvin at room temperature. Silver is the material with the second-highest thermal conductivity at 429 watts per meter per degree Kelvin. This makes silver the metal with the highest condu
Some of the worst conductors of electricity include rubber, polymer and plastic. A bad electrical conductor is an object or material that does not allow electricity to flow freely through it. An insulator does not allow electric current to pass through it. Most metals, such as copper, are good condu
Oil, fur, silk, wool, rubber, glass, plastic, wood, paper, wax and ebonite are good insulators. Insulators are substances with tightly bound outer electrons and heavily resist the flow of electrons. Most nonmetals are classified as insulators.
The most accessible and affordable home insulator is rolled fiberglass, and the most effective insulator is closed cell foam, according to HGTV. Cotton batts are a comparable option.
One example of a science project involving insulation is to measure the effects of an insulating container on the transmission of heat from a warm beverage. The comparison involves measuring temperatures at which people could comfortably pick up a cup of that beverage, using cups made of different m
Non-conductors of electricity are also known as insulators. Insulators do not allow a significant amount of electrical current to flow through. Some examples of insulators are glass, rubber and plastic.
Silver is the best metal conductor, but graphene is the best overall material at conducting electricity. Graphene consists of carbon atoms arranged in extremely thin sheets, and has the lowest electrical resistance of any commonly known material.
Insulation slows or prevents heat, sound, electricity, mechanical vibration or radiation from coming through walls. There are four types of insulation: heat insulation, sound and vibration insulation, electrical insulation, and radiation insulation.
