The Capacitance, also known as the Capacitance, refers to the charge storage at a given potential difference. The symbol is "C". The SI unit is Farad. The commonly used capacitance units are millimetric (mF), micrometric (μF), nanometric (nF) and cuticle (pF). The specific conversion method is as follows: 1 farad (F) =1000 milieu (mF) =1000000 micromethod (μF) 1 micromethod (μF) = 1000 nano method (nF) = 1000000 skin method (pF). Capacitors are mainly used in power filtering, signal filtering, bypass, … Continue reading "Understanding capacitor elements"

So-called integrated circuit technology, is the transistors, diodes, resistors, capacitors and so on certain process will be needed for the circuit elements such as transistors, diodes, resistors, capacitors, and then use the proper process for interconnection, then encapsulated within the shell, the volume of the whole circuit is greatly reduced, the number of wires and welding point is greatly reduced. So what are the manufacturing processes of integrated circuits? 1. Monolithic integrated circuit process Using grinding, polishing, oxidation, diffusion, lithography, … Continue reading "What are the integrated circuit processes?"
Current sensor, is a kind of detection device, can feel the information of the measured current, and can be detected and feel the information, according to a certain law to meet a certain standard of electrical signal or other required form of information output, in order to meet the transmission, processing, storage, display, recording and control of information and other requirements. Next, I will tell you in detail how the current sensor works how the current sensor is wired First, … Continue reading "Working Principle of the current sensor How to connect the current sensor"
The Hardware stamping process can be divided into two categories: hot stamping and cold stamping. Metal stamping hot stamping is to heat metal materials to a certain temperature range of stamping processing method. The characteristics of hot punching are: can eliminate internal stress, avoid work hardening, increase the plasticity of materials, reduce deformation resistance, reduce the power consumption of equipment. Cold stamping refers to the processing of metal materials at room temperature, generally applicable to billets with thickness less than … Continue reading "Metal stamping process classification"
During communication, there are two causes of terminal resistance signal reflection: impedance discontinuity and impedance mismatch. Impedance discontinuity, the signal at the end of the transmission line suddenly meets the cable impedance is very little or no, the signal will cause reflection at this point. The principle of signal reflection is similar to the way light is reflected from one medium to another. To eliminate this reflection, a terminal resistance of the same size as the characteristic impedance of the … Continue reading "Do you know the reflection principle of terminal resistance signal?"
In this day and age, you may not have a watch, but your home must have an electricity meter. The electricity meter, as a measuring instrument related to people's livelihood, is an essential tool for electricity metering and electricity bill settlement. Have you looked closely at your own electricity meter? Does your home use a traditional mechanical meter or a smart meter? Do you have any questions about electricity meters? Next, Xiaobian to roughly summarize some common sense problems of … Continue reading "Things you didn't know about electricity meters"
What is the terminal resistance? Terminal resistance is an obstacle encountered in the transmission of electronic information. When high-frequency signals are transmitted, the signal wavelength is shorter than that of the transmission line, and the signal will form reflected waves at the terminal of the transmission line, interfering with the original signal. Therefore, terminal resistance should be added at the end of the transmission line, so that the signal will not reflect after reaching the end of the transmission line. … Continue reading "What is terminal resistance?"
Today Xiaobian to introduce the difference between the following four kinds of resistance: 1, insulation resistance A DC voltage is applied to the medium. After a certain time of polarization, the corresponding leakage current through the dielectric is called insulation resistance. Insulation resistance is the most basic insulation index of electrical equipment and electrical circuit. Low voltage electrical equipment handover test, motor, distribution equipment and distribution line insulation resistance shall not be less than 0.5 mω (operating equipment and wiring … Continue reading "What are the differences between the four common resistors?"
What is a relay? A relay is an electrical control device that has an interaction between a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. It is actually a control circuit using small current to control the operation of large current "automatic switch". Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit. Its working principle is to … Continue reading "One minute takes you to learn about relays"
