Although magnetic fields may not play a big role in some circuit designs, EMI and EMC in PCB design are of great help, and these contents are useful in wireless charging circuits.

When the capacitance value we want is not available on hand, we can get it by connecting capacitors in series and parallel. A characteristic of the capacitor can be obtained by charging and dischargin'...

This article focuses on the detection of capacitors with an analog multimeter, as well as the functions of capacitors, such as bypass, decoupling, filtering, etc. Capacitors have two major characteris'...

There are many types of capacitors. When we design, we generally only use a few commonly used capacitors. Many types are rarely used. Below I will introduce the following commonly used capacitors.

Resistors are the most common components in circuits. Whether you are doing questions or circuit design, you will face a problem: how to judge the quality of resistors. Let's take a look at how to det'...

The superposition principle is an important analysis method for linear circuits. A linear circuit is a circuit in which voltage and current are proportional.

Any linear active two-terminal network can be simplified to a voltage source according to Thevenin's theorem, as shown in the figure below, the content of Thevenin's theorem: An active two-terminal ne'...

Kirchhoff's law is for complex circuits. Complex circuits refer to circuits that cannot directly use the rules of series and parallel circuits to find various parameters of the entire circuit. They ar'...

Introduction and functions of series, parallel and mixed circuits of resistors

When electric current flows through a certain material, the material current has a certain hindrance. This hindrance is the resistance of the material. The resistance of a conductor, when the material'...

What the editor is talking about today is about learning physics, or learning basic knowledge of electronic technology, which can also be regarded as some common sense in life.

A circuit is made up of various devices connected together. To sum up, a circuit is a whole composed of various components connected in a certain way.
