Textbook for Operation and Maintenance Engineer of Power and Environment Specialty of Data Center - Resistance and Resistance Law - Classification of Materials

According to the strength of the conductivity of materials, they can generally be divided into conductors, insulators and semiconductors.
The outer electron attraction of the atomic nucleus of the conductor is very small, and the electrons are easy to break away from the atomic nucleus and form a large number of free electrons. All conductors can conduct electricity, such as silver, copper and aluminum. smart rack Smart cabinet server rack network rack Network cabinet wall mounted cabinet Open Racks Frame rack accessories rack tray blank panel spacer

Insulators cannot conduct electricity, such as glass, bakelite, ceramics, mica, etc.
The conductivity of semiconductor is between conductor and insulator, such as silicon, germanium, etc.
