Electronic components are the basic building blocks in electronics and they are able to process electrical signals in different ways. In this article, we will introduce some common electronic components, their main roles and their working principles. This article summarizes some information that we hope will provide readers with valuable references.

I. Resistors

A resistor is a component used to control the current and voltage in a circuit, and its role is to impede the flow of current. Resistors have two main parameters: resistance and power. The resistance value is the size of the resistor to impede the flow of current, and the power is the maximum power that the resistor can withstand. The resistor works by using the resistance of the material to impede the flow of current through the collision and rebound of electrons.

II. Capacitor

A capacitor is a component that stores electrical charge. Capacitors have two main parameters: capacitance and voltage. Capacitance is the size of the capacitor's ability to store charge, and voltage is the maximum voltage the capacitor can withstand. The working principle of capacitor is to use the medium between two conductors to isolate the charge, forming an electric field and storing electrical energy.

Three, inductors

Inductor is a component that stores magnetic energy, and its role is to control the change of current and voltage. Inductors have two main parameters: inductance and current. Inductance is the size of the inductor's ability to store magnetic energy, and current is the maximum current the inductor can withstand. Inductors work by using current to generate magnetic flux in a magnetic field, which stores magnetic energy.

Fourth, the diode

A diode is a semiconductor component that serves to limit the flow of current in one direction. Diodes have two electrodes: positive and negative. The positive electrode is the direction of current inflow and the negative electrode is the direction of current outflow. The diode works by using a PN junction in the semiconductor, which allows current to pass when a positive voltage is applied to the PN junction, and is impeded when a reverse voltage is applied to the PN junction.

V. Transistor

A transistor is a semiconductor element that serves to control the flow of current. A transistor has three electrodes: emitter, base and collector. The emitter is the direction of current outflow, the collector is the direction of current inflow, and the base is the direction that controls the flow of current. The working principle of transistor is to use the base input signal to control the size of collector current, so as to realize the function of signal amplification or switching control.

Sixth, the field effect tube

Field effect tube is a semiconductor component, its role is to control the flow of current. Field-effect tube has three electrodes: source, gate and drain. The source is the direction of current outflow, the drain is the direction of current inflow, the gate is to control the direction of current flow. The working principle of FET is to use the gate voltage to control the size of the source-drain resistance to achieve the function of signal amplification or switching control.

Seven, integrated circuits

Integrated circuit is a micro circuit board formed by integrating many electronic components (such as transistors, capacitors, resistors, etc.) together, which serves to achieve complex circuit functions. Integrated circuits are usually divided into two types of digital integrated circuits and analog integrated circuits. Digital integrated circuits are mainly used in digital circuits to realize logic operations and control functions; analog integrated circuits are mainly used in analog circuits to realize functions such as signal processing and amplification.

The electronic components introduced above are the basic building blocks commonly used in electronics technology, and they can process electrical signals in different ways to achieve different functions. Different electronic components have different working principles and parameters, and need to be selected and designed according to actual needs. In the development of electronic technology, new electronic components are constantly emerging, which not only expand the scope of application of electronic technology, but also provide more possibilities for the development of electronic technology, ICGOO website will continue to update the articles to provide the latest technical information and product information to help users understand and select the most suitable components for their needs.
