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 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 ...
As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...
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 ...
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 ...
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 ...
‘The Current War: Director’s Cut’ shows how the electric power system we take for granted came to be
Professor, Tepper School of Business, Engineering and Public Policy and Co-Director, Carnegie Mellon Electricity Industry Center, Carnegie Mellon University Jay Apt and the Carnegie Mellon University ...
The project comprises 1,000 MW of alternating current (AC) capacity, equivalent to 1,400 MWp of direct current (DC) capacity.
ACTIVE nitrogen has been generally investigated at pressures of several tenths of an mm. The majority of workers have used either a condensed or electrodeless discharge to produce the active species 1 ...
