Semiconductors help to transmit conductivity between insulators and conductors. They can be in natural forms or may be a manufactured electronic.Know More
Semiconductors are naturally found in nature. Elements like germanium and silicon are considered semiconductors. Compounds like cadmium selenide or arsenide are also semiconductors. Making minor changes to these elements or compounds can greatly change their ability to transmit conductivity.
Semiconductors are essential to the operations of electronics like microwave ovens, radios, watches and telephones. This is because when semiconductors are manufactured, it's easy to control the amount of electricity that they transmit, which contributes to the overall function of the device. Because of this, they are essential to the functions of key materials like circuits and transistors.Learn more about Electricity
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.Full Answer >
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.Full Answer >
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.Full Answer >
