Recently, Lown and his co-workers 5 showed that in dogs a direct-current discharge from a storage capacitor was safer and more effective than alternating-current countershock.

Despite the dominance of alternating current in our day to day lives, direct current still has some very useful applications.

The same phenomenon applies when electricity is converted to kinetic energy in a motor or you shift between direct and alternating current in power electronics. All of this brings us back to the Volt.

Numerous examples are given to illustrate the principles of direct current and alternating current machinery and in addition there is a selection of problems, at the end of most chapters, which ...

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 ...

Almost everything we use runs on direct current, so why are our houses still wired for alternating current?

High-voltage direct current (HVDC) technology offers more efficient bulk power transfer over long distances compared to alternating current (AC) systems.

AC and DC are simply the abbreviations of alternating current (AC) and direct current (DC), used in reference to electrical systems and the way electricity travels throughout the circuit.

ABB has achieved another significant milestone with the commissioning of the Xiangjiaba-Shanghai project, the world’s first UHVDC (ultrahigh-voltage direct current) transmission link to go into ...

The Function of an Inverter Broadly speaking, an inverter is an electrical device that converts electricity derived from a DC (Direct Current) source to AC (Alternating Current) of the type that ...
