How do Transistors Work?10 August 2020
A transistor is a kind of semiconductor device that controls current. Its function is to amplify the weak signal into an electrical signal with a larger amplitude value, and it is also used as a contactless switch.
What is Electronic Ballast?28 September 2020
Electronic Ballast is a kind of ballast, which uses electronic technology to drive the electric light source to produce the required lighting. Corresponding to it is the inductive ballast. More and more modern fluorescent lamps use electronic ballasts, which are light and compact, and people can even integrate electronic ballasts with lamps.
What is Regulated Power Supply?08 January 2021
Regulated power supply is an electronic device that can provide stable AC or DC power to the load, including AC regulated power supply and DC regulated power supply.
How to make an Obstacle Avoiding Robot?29 August 2023
The article will tell you How to make an Obstacle Avoiding Robot.
Introduction to Servo System08 September 2021
Servo system is a product developed on the basis of frequency conversion technology. It is an automatic control system that takes a mechanical position or angle as the control object.
Introduction to Photonic Integrated Circuits and PIC Technology22 October 2025
The concept of the photonic integrated circuit is similar to the concept of electronic integrated circuits. However, electronic integrated circuits integrate transistors, capacitors, resistors, and other electronic devices, while PIC integrates various optical devices or optoelectronic devices, such as lasers, electro-optical modulators, photodetectors, optical attenuators, optical multiplexers/demultiplexers, and optical amplifiers.
What is an ASIC Chip?07 January 2026
ASIC (Application Specific Integrated Circuit) is a special-purpose integrated circuit, which is an integrated circuit designed and manufactured in response to specific user requirements and the needs of a specific electronic system.
An Overview of Isolation Transformers17 September 2020
An isolation transformer is a transformer in which the input and output windings are electrically isolated. The isolation transformer is to isolate the current of the primary winding and the secondary winding respectively.

What is a USB Data Cable?27 August 2021
The USB data cable is used for the connection and communication of the computer and external devices. It can also be used for the charging of the phone and the external connection. It is popular for transmitting data and charging.
What is a High-pass Filter?10 March 2021
A high-pass filter is a combination device of capacitors, inductances, and resistors that allow signal components above a certain frequency to pass, while greatly suppressing signal components below that frequency. The high-pass filter only attenuates the frequency components below a given frequency, and allows the frequency components above the cutoff frequency to pass, and there is no phase shift filtering process. Mainly used to eliminate low-frequency noise, also called low-cut filter.
Ohmic Resistors: Differences, Laws, and Applications08 June 2026
This article explores the fundamentals of ohmic resistors, which obey Ohm's Law and exhibit a linear voltage-current relationship. It contrasts them with non-ohmic resistors, whose resistance varies with voltage, current, or temperature. Key topics include graphical analysis, practical applications in circuits, and the impact of material choice and temperature. The article also highlights common pitfalls, real-world usage, and tips for selecting the right resistor. Understanding ohmic resistors is essential for effective circuit design, offering predictability, reliability, and simplicity across a wide range of electronic systems, from beginner projects to advanced engineering applications.
