1、 Components: products that do not change the molecular composition of raw materials during processing can be called components. Electronic components Components are devices that do not require energy. It includes resistance, capacitance and inductance. (also known as passive components) Elements are divided into: 1. Circuit components: diodes, resistors, etc. 2. Connecting components: connectors, sockets, connecting cables, printed circuit boards (PCBs), etc. 2、 Devices: The products whose molecular structure of raw materials has been changed during production and processing are called devices. Devices are divided into: 1. The main characteristics of active devices are: (1) self consumption of electric energy, (2) need of external power supply. 2. Discrete devices are divided into (1) bipolar crystal triode, (2) field effect transistor, (3) thyristor, (4) semiconductor resistor and capacitor. resistance The resistance is represented by "R" plus a number in the circuit, for example, R1 represents the resistance numbered 1. The main functions of resistance in the circuit are: shunt, current limiting, partial voltage, bias, etc. capacitance Capacitance is generally represented by "C" plus numbers in the circuit (for example, C13 represents the capacitance numbered 13). The capacitor is composed of two metal films close together and separated by insulating materials. The main characteristic of the capacitor is the direct current. The capacity of the capacitor indicates the size of the stored electric energy. The blocking effect of the capacitor on the AC signal is called capacitive reactance, which is related to the frequency and capacitance of the AC signal.

Electronic components
Components are devices that do not require energy. It includes resistance, capacitance and inductance. (also known as passive components)
Elements are divided into:
1. Circuit components: diodes, resistors, etc.
2. Connecting components: connectors, sockets, connecting cables, printed circuit boards (PCBs), etc.
2、 Devices: The products whose molecular structure of raw materials has been changed during production and processing are called devices.
Devices are divided into:
1. The main characteristics of active devices are: (1) self consumption of electric energy, (2) need of external power supply.
2. Discrete devices are divided into (1) bipolar crystal triode, (2) field effect transistor, (3) thyristor, (4) semiconductor resistor and capacitor.
resistance
The resistance is represented by "R" plus a number in the circuit, for example, R1 represents the resistance numbered 1. The main functions of resistance in the circuit are: shunt, current limiting, partial voltage, bias, etc.
capacitance
Capacitance is generally represented by "C" plus numbers in the circuit (for example, C13 represents the capacitance numbered 13). The capacitor is composed of two metal films close together and separated by insulating materials. The main characteristic of the capacitor is the direct current.
The capacity of the capacitor indicates the size of the stored electric energy. The blocking effect of the capacitor on the AC signal is called capacitive reactance, which is related to the frequency and capacitance of the AC signal.
