Components: products that do not change the molecular composition of raw materials during processing can be called components.
After the invention and mass production of transistors, various solid-state semiconductor components such as diodes and transistors were widely used, replacing the functions and roles of vacuum tubes in circuits. By the middle and late 20th century
Semiconductors are widely used in consumer electronics, communication systems, medical instruments and other fields. For example, diodes are devices made of semiconductors. The importance of semiconductors is enormous in terms of technology and economic development
Substances and materials in nature can be divided into three categories: conductors, semiconductors and insulators according to their conductivity. The resistivity of semiconductor is in the range of 1m Ω· cm ~ 1g Ω· cm (the upper limit is taken according to Xie jiakui's electronic circuit, and 1/10 or 10 times of it; because the angle mark is not available, the current description is used temporarily)
Commonly used electronic components are: resistance, capacitance, inductance, potentiometer, transformer, diode, triode, MOS tube, integrated circuit, etc.
