Examples Of Electrical Conductors And Insulators

Some insulators eg glass are poor conductors when cool yet good conductors when hot. Conductors carry electric current.

Science Electricity Conductors And Insulators English

Conductors and insulators are both important in the field of electronics.

Examples of electrical conductors and insulators. Some of the common conductor examples include metals such as. Whether a material is a conductor or an insulator depends on its atoms and on the relationship of each atom to its surrounding atoms. The wire in the center is typically made of copper and the outer jacket is made from plastic or rubber.

These materials are called insulators. Conductors are on the other hand metals in general. The property which makes insulators different from conductors is its resistivity.

Some common conductors are copper aluminum gold and silver. Some good conductors become superconductors at extremely low temperatures. Insulators protect conductors and protect people from conductors.

Most metals are better conductors when cool and less efficient conductors when hot. Some common insulators are glass air plastic rubber and wood. If we speak in terms of electrical conductivity some good insulators are ceramics plastics rubber and glass.

Insulators oppose electrical current and make poor conductors. Wood cloth glass mica and quartz are some good examples of insulators. Graphite the human body and the earth are good conductors of electricity.

An electrical cord is made of both conductors and insulators. Conductors conduct electrical current very easily because of their free electrons. Other materials are resistant to the flow of electric current.

As temperature increases atoms and their electrons gain energy. Insulators are also protectors as they give protection against heat sound and of course passage of electricity. Electrical conductors allow electric current to flow easily because of the make up of their atoms.

Copper silver gold but there are some good conductors that are not metals like graphite and some salt solutions.
