At present, direct current is often used in lighting applications.
Alternating current didn't seem as useful as direct current, but then in 1883 a Croatian electrical engineer, Nikola Tesla (1856-1943), constructed an induction motor that could make use of alternating current to do useful work.
The battery is then used through a direct current wiring system that complements grid wring.

Virginia) explain the direct numerical simulation of the transport under a direct current electric field using continuum-based mathematical models and the commercial finite element software package COMSOL Multiphysics.
They promise low direct current resistance (DCR) ratings, excellent thermal efficiency, and current ratings up to 11 amps direct current (ADC).
The conductors atop the electrical transmission towers carry 500,000 volts, the highest voltage line in DWP's equipment and one that carries direct current, not alternating current, Yancy said.
In the battle between alternating current and direct current (see 1883), victory went to alternating current, because it could be transformed into another current of much higher voltage and of correspondingly lower amperage (to get something, you have to give up something in the real world).
The first standard guideline in characterizing a superconductor is observing a total loss of resistance to a direct current.
Process industries such as packaging, pharmaceuticals, and food processing have begun to increasingly adopt motor technologies, with alternating current (AC) offerings stealing the march over direct current (DC) products.
Their topics include semiconductor power switches and passive components, the control of power electronic devices, line-commutated converters, conversion from direct current to direct current, inverters and alternating-current converters based on completely controllable switches, pulse-width modulation and power quality control, resonant converters, and applications of power electronics.
