Introduction to Basic Electrical Theory: Circuit Theory
Electric circuit theory is one of the most vital aspects of electrical engineering. Understanding how components work individually and collectively is the basis for designing, manufacturing, and troubleshooting all kinds of electronic devices and systems. This article will cover the basic circuit components, laws, and parameters in electrical engineering.
An Introduction to Embedded Design and Development: Define and Understand Embedded Systems and Design
In the electronic engineering and computer science fields, several terminologies evolve and become popularised without many people understanding what they mean. For those curious to learn more about embedded systems, this article explains some of the elaborate terms.
Pushing the Limits of Power Generation: Harvesting Electric Power from Rust
Researchers at the California Institute of Technology and Northwestern University have discovered a way to generate electric power from a thin coating of rust. What does this solution mean for us, and can it have a meaningful impact on sustainable power generation in the future?
Understanding and Minimising Power Loss in Electric Devices and Power Systems
Many types of power losses can occur in electric circuits for a multitude of reasons: troubling electrical engineers (EEs), they cause a host of problems that affect the efficiency, reliability, and safety of the systems that EEs design and build. Understanding how and where these losses occur—including heating, eddy current, and switching losses—can help engineers to keep them at a bare minimum.
The Appeal Behind Designing Low-Power Electronics
In 1947, William Shockley, alongside a team of physicists at Bell Labs, demonstrated the first practical transistor, one of the earliest efforts at low power electronic design. The transistor replaced the bulky and energy-demanding vacuum tubes used at the time and paved the way for smaller electronics with lower power consumption.
The First Programmable Memristor Computer: Impacts on Machine Learning and AI Industries
Until now, memristors have primarily been a solution looking for a problem. In a recent development, however, researchers from the University of Michigan claim to have built the first programmable memristor computer.
Circuit Protection Devices That Ensure the Safety and Reliability of Electrical Circuits
Every electrical engineer charged with the responsibility of designing and building electrical systems must ensure that they are reliable, safe, and durable. But sometimes, things could go awry: burnt PCBs and components, static shocks, and tripped circuit breakers are just some of the myriad technical issues that come from inadequate circuit protection.
Wireless Health Monitoring Using Integrated and Stretchable Electronics
The wireless, wearable adhesive-free monitor with integrated stretchable electronics could facilitate comfortable, long-term health monitoring without the risks of skin irritation, injury, or allergic reactions that current adhesive sensors carry.
The ‘Beyond 5G’ Wireless Transceiver and The Future of High Speed Connectivity
A new radio chip from the University of California, Irvine (UCI), may have already paved the way for futuristic 6G, despite 5G cellular network standard still being in its infancy. Developed by electrical engineers at UCI’s Nanoscale Communication Integrated Circuits labs, the product promises to deliver up to 4 times greater speed and significantly higher bandwidth than 5G.
Strategies for Minimising Electromagnetic Interference in Electronic Systems
Electromagnetic interference (EMI), aka 'electrical noise', is one of the most common problems observed in a variety of electrical and electronic circuits. Any kind of circuit that carries rapidly-changing electric currents is prone to electromagnetic (EM) disturbances via stray EM fields.
How AR and AI Advancements Are Impacting Multiple Industries
AI has also emerged as a key player in the engineering realm. Businesses are increasingly pursuing automation, which is AI’s calling card. Such algorithm-based cognitive tasks can be time-consuming for humans. AI development constitutes an exciting new engineering frontier to explore as technology evolves. Both AR and AI are transforming the global productivity landscape.
The Leading Developments in Next Generation Batteries
Batteries are the subtle powerhouses behind modern electronics. They function essentially to provide startup currents to varying loads and store charges to provide reserve power for portable or grid-scale operation. Lithium-ion batteries, which are the predominant type, pose a number of issues for devices including overheating, limited charge/discharge cycles, and safety concerns.
