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 ...

Even though today most of the electricity transmission lines are alternating current ones, in some cases direct current lines are also used. Scientists have been working to improve the technology ...

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 ...

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 ...

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 ...

TalTech spin-off DCR Technologies is building a bridge toward the power grids of the future. Much of today’s technology already relies on direct current (DC). Solar panels generate DC power, and it is ...

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 first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...
