Inductor Basics: Structure, Parameters, and Measurement24 October 2025
Inductors are components that can convert electrical energy into magnetic energy and store it. An inductor generally consists of a skeleton, a winding, a magnetic core, an iron core, a shielding case, and a package. Commonly used inductors are adjustable inductors and choke inductors. In the circuit, the inductor prevents the AC and allows DC to pass through.
Basic Introduction to Photocell09 April 2025
This article addresses a photocell description that includes the process, circuit diagram, forms, and applications of the photocell. The photocell is essentially a kind of resistor that can be used to adjust its resistive value depending on the strength of light. These are cheap, easy to procure as well as specifications in various sizes. Compared with other units, each photocell sensor can work differently, even though they're from the same family.
How do Inductors Work?27 October 2025
Inductors are energy storage elements that convert electrical energy into magnetic energy for storage. It is similar to a transformer, but the inductor has only one winding. The structure of an inductor is generally composed of a skeleton, a winding, a shield, the packaging material, an iron core, and a magnetic core.
Comparing Bridge Rectifiers and Full Wave Rectifiers for Beginners09 June 2026
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.
What is Time Delay Relay?18 December 2025
Hello everyone, I am Rose. Today I will introduce Time Relay to you. A Time Relay is an electrical component that is used on a circuit with a lower voltage or lower current to turn on or off a circuit with a higher voltage and bigger current or to regulate a higher voltage or larger power. This article will introduce some basic knowledge of Time Relay.
Capacitor Basic: How do Capacitors Work?18 April 2025
This comprehensive guide explores the fundamental principles of capacitors, explaining how they store electrical energy by accumulating charges on metal plates separated by dielectric materials. The article details the charging and discharging processes of capacitors, alongside a thorough explanation of capacitance units and practical size considerations that affect their energy storage capabilities. Additionally, it outlines twelve key applications of capacitors in electronic circuits, including filtering, coupling, tuning, and motor operation, demonstrating their essential role in modern electronics.
What is FPC (Flexible Printed Circuit)?26 December 2025
Flexible Printed Circuit (FPC) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, lightweight, thin thickness, and good bendability.
What is Color Ring Inductor? How to Read Inductor Color Code?01 April 2025
Hello everyone, I am Rose. Today I will introduce color ring inductor to you. A color ring inductor, also known as a color code inductor or a color ring inductor, is a self-inducting component. Together with a capacitor, the inductance coil (color ring inductance) frequently creates a resonant and filter circuit in the circuit.
How to Use the Oscilloscope's X-Y Display Correctly19 September 2022

Comprehensive Introduction to Snapdragon 88828 June 2021
Snapdragon 888 is the mobile phone processor of Qualcomm Company. On December 1, 2020, at the Snapdragon Technology Summit held in Hawaii, Qualcomm announced the launch of the latest generation of flagship SOC-Qualcomm Snapdragon 888 5G mobile platform and Snapdragon X60 5G baseband.
Introduction to Pi Filter19 February 2021
A Pi filter is a type of filter with a two-port, three-terminal block consisting of three elements with two terminals in each element: the first element is connected to the GND terminal via i/p, the second terminals are connected to the terminals from i/p to o/p and the third element is connected to the terminals from o/p to GND. The circuit model is going to be like a 'Pi' symbol. Capacitors and one inductor are the elements used in the circuit.
