AC and DC power differ in direction, usage, and efficiency. Learn the basics of how alternating and direct current work and where each is used.

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

These convert direct current into alternating current, allowing DC batteries the capability to supply power to numerous locations even in the event of an interruption in the AC supply.

Circuit breakers are a safety feature that automatically interrupts the flow of electricity in the face of a system fault or ...

The reduction of phthalimides using alternating-current electrochemistry yields a cleaner crude NMR compared with direct-current alternatives.

A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a novel strategy to reduce friction and wear by inducing dynamic ...

A Powerful Alternative to Alternating Current Ultra-high-voltage direct current takes electricity farther with less loss.

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 ...
