Inductance Basis: Definition, Structure and Applications18 April 2022
Hello everyone, I am Rose. Today I will introduce inductance to you. Inductance is a property of a closed loop and a physical quantity. It is a circuit parameter that describes the induced electromotive force effect in this coil or in another coil due to changes in coil current. Inductance is a general term for self-inductance and mutual inductance. A device that provides an inductance is called an inductor.
Introduction to AC motor05 March 2021
The motor which uses an electromagnetic induction phänomen to convert the alternative current into mechanical power is called an AC motor. An alternating current drives this motor. Two main components of the AC motors include the stator and the rotor. The stator is the motor's permanent component, and the rotor is the revolving part of the motor. The AC motor can be single or 3-phase.
Ultimate Guide to KVM Switches: Definition, Usage, and 2025 Trends18 December 2025
Hello, I am Rose. Welcome back to the new post today. KVM stands for keyboard, video and mouse. The so-called KVM is also called a multi-computer controller, and the official name is a multi-computer switch. A KVM switch is a hardware device that allows users to control 2, 4, 8, 16, or even more than 4096 computer hosts through a set of keyboards, video monitors, and mice.
What are the Types of Audio Cables?27 October 2021
Today, I will introduce you to some common audio cables. I hope you will have a new understanding of the cable of the audio equipment.
Introduction to Step-down Transformers14 October 2020
The step-down transformer is a transformer that converts the higher voltage at the input terminal into an ideal low voltage output, so as to achieve the purpose of step-down. The step-down transformer is a very important equipment in the power transmission and transformation system. Its normal operation not only relates to its own safety and reliable power supply for users, but also directly affects the stability of the power system...
Comparing Bridge Rectifiers and Full Wave Rectifiers for Beginners05 July 2025
Bridge rectifiers use four diodes and no center-tapped transformer, while full wave rectifiers need two diodes and a center tap. Compare their pros for beginners.
LVDT - Linear Variable Differential Transformer Basics16 January 2021
LVDT is the abbreviation of linear variable differential transformer, which belongs to linear displacement sensor. It is a movable iron core transformer that consists of a primary coil, two secondary coils, iron core, coil frame, shell and other components.
Infrared Thermometer: How it Works? How to Use it?12 August 2021
Infrared thermometers are divided into fixed thermometers and hand-held thermometers. They are a kind of thermometer that detects the amount of infrared rays on the surface of an object to achieve temperature measurement.
What is a Voltage Controlled Oscillator?09 January 2026
Voltage controlled oscillator (VCO) refers to an oscillator circuit whose output frequency corresponds to the input control voltage. The operating state of the oscillator or the component parameters of the oscillation circuit are controlled by the input control voltage. The frequency of the VCO has a linear relationship with the control voltage. It is an important part of PLL.
Introduction to Silicon Controlled Rectifier25 September 2020
Silicon Controlled Rectifier, abbreviated as SCR, is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power drive device to realize the control of high-power equipment with low-power controls. It has been widely used in AC and DC motor speed control system, power control system and servo system.
Basic Introduction to Hall Effect Sensors13 November 2025
The Hall effect sensor is a magnetic field sensor made according to the Hall effect. The Hall effect is a type of magnetoelectric effect. This phenomenon was discovered by Hall (A.H. Hall, 1855-1938) in 1879 when he studied the conductive mechanism of metals.
