Rubber is a good insulator because it prevents electrons from moving through it easily and gaining energy, which causes an electrical charge. Electrons are transferred to rubber, but they cannot move fast enough to gain the energy they need to disperse an electrical charge.Know More
Because rubber is a good insulator, it is used on the outside of wires that are used to conduct electricity. An insulator is a material that reduces or stops the flow of an electrical current. Rubber provides protection from the dangers of electrical charges being carried through the metal conductors.
In rubber, the electrons are tightly bound within the material, which means that they are not free to be shared by neighboring atoms. The properties of rubber allow the electrons to slow down. In some cases rubber can completely prevent electrons from moving.
Electrical cords are a good example of rubber being used as an insulator. If a cord is frayed and has damaged the outer rubber lining, the rubber will not be an effective insulator. If the conductors (wires) are exposed, it is necessary to replace the cord.
Keeping electricity bound within the material is the primary goal of an insulator, and because of this, rubber is a very good choice.Learn more about Chemistry
Rubber does not conduct electricity. In fact, it is generally known as an effective insulator and is widely used in gear designed to prevent electrocution. The only solids that conduct electricity are metals and graphite.Full Answer >
According to HowStuffWorks, aluminum foil is a good insulator because it prevents the radiation of heat by reflecting it back at the source. Since aluminum foil reflects the emission of heat, it tends to be a better insulator than other materials that just slow down the flow of heat from one area to another.Full Answer >
Every atom is made up of a nucleus surrounded by electrons that orbit the nucleus. Electrons orbit the nucleus because they are attracted to the protons inside of the nucleus while simultaneously repelled by the other electrons.Full Answer >
The two most common elements found in natural rubber are carbon and hydrogen. Eighty percent of the world's natural rubber supply is cultivated from rubber trees that grow in tropical climates such as Thailand, Indonesia and Malaysia. Rubber tree plantations can yield 30 to 35 grams of rubber per tree in a single day, which is then used in products such as heavy duty tires.Full Answer >
