In the previous article, we looked at how electricity is generated and how it reaches us through power lines. In this article, we will look at alternating current (AC), which was mentioned many times.

Researchers kept a 70-cell solid oxide steam electrolysis stack running for 25,000 hours with record-low degradation by ...

A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a novel strategy to reduce friction and wear by inducing dynamic electronic ...

Including all the essential information on circuit design, as well as techniques and tricks of the trade, this hard-working reference will be an engineer's first port of call for key information, ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

Electric vehicles are an important wave of the future, offering motorists a cleaner and more efficient way to travel. But when it comes to charging their batteries, electric vehicles have a particular ...

This tutorial will showcase how inductance, capacitance and resistance affect alternating current. A circuit may have the alternating current through it and the voltage across it rising and failing ...

The current U.S. transmission system will need to be upgraded and expanded to make it possible to carry larger amounts of clean energy across longer distances. In a short video, NREL explains four ...

Current transformers or CTs are indispensable anywhere high currents are measured and processed. These instrument transformers effectively diminish high-voltage current flows for a convenient way to ...
