What are electronic components? There are many types of electronic components. According to the nature of use, they can be divided into: resistors, capacitors, inductors, transformers, light-emitting diodes, crystal diodes, transistors, semiconductors, optocouplers, integrated circuits, relays, etc.
What do electronic components include?
Common are resistors, capacitors and inductors, let’s take a look!
1. Resistor, resistor is a very old and commonly used electronic component. A resistor is a device that limits the amount of current and is defined as a lead wire. According to different materials, it can be divided into metal film resistors, carbon film resistors, metal oxide resistors, wire wound resistors, etc. According to the role of different functions, it can also be divided into: color ring classification method, nominal value method, frequency method, voltage method, etc.
2. Capacitors, in electronic circuits, capacitors are devices that store charge. It can isolate AC or DC, and achieve the purpose of controlling the circuit by charging or discharging AC or DC.
3. Inductance, in the power circuit, the inductance is an energy storage element, which can be used to convert the power supply into inductance and impedance. Inductance has two main functions in the circuit, one is the transmission function, and the other is the resistance and inductance function, also called the anti-interference function.
4. Light-emitting diodes, simply speaking, are a special semiconductor material. Since it contains two tiny metal electrodes, the distance between the two electrodes is small, so the light-emitting diode has unidirectional conductivity. When a forward bias is applied, it emits light, and vice versa.
