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 ...

In Applied Physics Letters ( "Investigation on fabrication and physical mechanisms of single-contact AC-driven nano-LED ...

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 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 ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

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 ...

AT the present time electricians are interested in the problem of the change-over from direct current to alternating current systems of supply. Where new systems are being laid down in Great Britain ...

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 ...
