Electronic components are the basic building blocks of electronic circuits and are used to construct
various circuits that enable electronic products to perform various functions. The following are common
electronic components and their main functions:
1. Capacitor: used for storing charge, smoothing voltage, filtering, delaying, etc.
2. Resistor: used for limiting current, changing voltage, dividing voltage, regulating current, etc.
3. Diode: used for rectification, voltage stabilization, switching, etc.
4. Transistors such as thyristors and triodes: used for signal amplification, current control, switching, etc.
5. Integrated circuits (ICs): integrate multiple electronic components to achieve complex circuit functions.
6. Sensors: convert various physical quantities into electrical signals, such as temperature, humidity, light intensity, pressure, etc.
Electronic components are widely used in various electronic products such as computers, mobile phones,
