Ohmic Resistors: Differences, Laws, and Applications06 August 2025
This article explores the fundamentals of ohmic resistors, which obey Ohm's Law and exhibit a linear voltage-current relationship. It contrasts them with non-ohmic resistors, whose resistance varies with voltage, current, or temperature. Key topics include graphical analysis, practical applications in circuits, and the impact of material choice and temperature. The article also highlights common pitfalls, real-world usage, and tips for selecting the right resistor. Understanding ohmic resistors is essential for effective circuit design, offering predictability, reliability, and simplicity across a wide range of electronic systems, from beginner projects to advanced engineering applications.

EMC can also observe the waveform with an oscilloscope?04 March 2022
What's the difference between EMC's near field and distant field? Let's talk about it together today! EMC, also known as electromagnetic compatibility, is a complete assessment of an electronic product's electromagnetic field interference (EMI) and anti-interference capabilities (EMS), and is one of the most important indicators of product quality.
Development Board History and Differences from Single Board Computers (SBCs)16 May 2022
Hello everyone, I am Rose. Welcome to the new post today. In this article, we'll explain what the term "development board" (Figure 1) means and show how they differ from the closely related single-board computer (SBC, or single-board computer). We also map their evolution from the past to the present and discuss some trends in how they will evolve in the future.
Why Meta Did Not Choose Qualcomm AI Chip?02 April 2022
On April 1, it was reported that Qualcomm is the world's largest supplier of smartphone processors and is well-established in terms of computing power and energy efficiency of its chips. 2019 Qualcomm announced that it will enter the fast-growing market of data center AI chips based on its technology and experience in smartphone chips.
Can ARM challenge X86 in the field of PC chips？06 June 2022
More than twenty years ago, Microsoft's Windows operating system and Intel's X86 chip swept the entire computer market, until they met Apple. apple's rise to prominence made the once unbreakable Wintel camp crack, "Windows + X86" is no longer the only option. You can also choose "macOS + X86". And in 2020, the release of the M1 chip will also pull the ARM architecture into the battle, X86 ushered in a new competitor.

What is Chip: Definition, Classification and Design Process17 January 2026
Hi fellas. I am Rose. Today I will introduce the process of designing chips for you. Chips, also known as integrated circuits or VLSIs, are electronic circuits made up of thousands, millions, or even billions of transistors, resistors, and capacitors.
What are Comparators?03 December 2020
Comparing two or more data items to determine whether they are equal, or determining the size relationship and arrangement order between them is called comparison. A circuit or device that can realize this comparison function is called a comparator.
What is a Motor Starter?26 December 2025
A motor starter is an electrical system used to safely start and stop a motor. Like a relay, the motor starter turns power on/off, which offers low voltage and overcurrent safety, as opposed to a relay.
