I am Kevin Chen, I graduated from University of Electronic Science and Technology of China in 2000. I am an electrical and electronic engineer with 23 years of experience, in charge of writting content for ICRFQ. I am willing use my experiences to create reliable and necessary electronic information to help our readers. We welcome readers to engage with us on various topics related to electronics such as IC chips, capacitors, resistors, inductors, circuit breakers, diode, transistor, module, relay, opticalcoupler, connectors, PCBs, etc. Please feel free to share your thoughts and questions on these subjects with us. We look forward to hearing from you!
The cathode ray oscilloscope is a piece of laboratory equipment that may be used to examine the waveforms of alternating currents and voltages and measure voltage, current, power, frequency, and nearly any other variable involving amplitude and waveform. The screen displays the amplitude of electrical signals as a function of time. It’s commonly used for…
Standard wall switches provide simple on-off control of light fixtures. On the other hand, Dimmers allow you to alter the amount of power a fixture receives, changing the lighting intensity. A rheostat—a big variable resistor—was used in older dimmers. As the rheostat’s resistance grew, the voltage to the lamp was reduced, and the energy that…
A network switch serves as the system’s ” brain when it comes to network design. ” Networking hardware connects all devices on a LAN (Local Area Network) and redirects and forwards data to the correct location. When it comes to running a business, it’s critical to have a network switch that can successfully meet all…
The ATtiny85 is an 8-bit RISC microcontroller that is widely popular. Because of its great functionality in such a compact size has become the primary choice for professionals and developers. It’s an 8-pin (PDIP) microcontroller with nearly all of the functionality that any microcontroller should have, including built-in FLASH, EEPROM, SRAM, SPI, IIC, ADC, etc.…
Video cards and graphics cards are two of the most important pieces of hardware in your computer. They’re both used for rendering images on your screen, but they do it in slightly different ways. However, both video cards and graphics cards serve the same general purpose: to help improve visual performance by providing the computer…
Computer networking is a complex world. There are endless combinations of protocols, standards, and other variables to consider when building out your home or office network. And if you’re like most people, you probably have no idea what half of those things mean. Fortunately, it doesn’t have to be that way. To get the details…
As exciting as solar batteries are, they’re not perfect. They have some limitations that make them less than ideal in some applications. Once their useful life is over, they need to be replaced with a new one rather than fixed. There’s also no way to store surplus solar power for later use, which means only…
Have you ever wondered why the length of Ethernet cables varies? What if an Ethernet cable’s length has an impact on its connectivity? The length of an Ethernet connection does affect its connectivity, which is known as attenuation. The maximum length of an Ethernet cable before the signal loss is called attenuation. The influence of…
MOSFETs are divided into two categories: NMOS and PMS. The main distinction between NMOS and PMOS is that NMOS uses n-type semiconductors for the source and drain terminals, whereas PMOS uses p-type semiconductors for the Source and drain terminal. This article describes the essential distinction between NMOS and PMOS MOSFET What is NMOS? NMOS…
There are numerous single-pole switches in every home. They’re used to turn 120-volt circuits for lighting, furnace disconnects, garbage disposals, and other appliances. Learn how to wire a single-pole switch with ease. You’ll be turning lights on and off in no time with this straightforward how-to. With a few essential electrical tools and these instructions,…
