There are two main types of electrical current that flow through your home: Alternating and direct. The vast majority of devices around you are powered by alternating current. By allowing electrons to ...

The world of electric vehicles can sometimes seem like it comes with its own vocabulary, and that's where we come in. Look out for our ABC of EVs series, to demystify the words and phrases you'll hear ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

You can't live without your smart phone charger. I understand that. However, the charger needs a DC supply. DC stands for Direct Current (this means that you can't say "DC Current" - that would be ...

Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.

Scientists at Scripps Research have used rapid alternating current (AC) to selectively reduce carbonyl groups (J. Am. Chem. Soc. 2021, DOI: 10.1021/jacs.1c06572). The technique avoids side reactions ...

China is hungry for power. A fast expanding middle class is driving relentless demand for electricity. Annual electricity consumption is growing by around 8 per cent, according to the Chinese National ...

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long ...

Poor Topsy. Thomas Edison killed the ex-circus elephant, electrocuting the animal to demonstrate how dangerous alternating current was. Edison even described electrocution as being “Westinghoused,” ...

THE winds of the Oklahoma panhandle have a bad reputation. In the 1930s they whipped its over-tilled topsoil up into the billowing black blizzards of the Dust Bowl. The winds drove people, Steinbeck’s ...
