A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the...

An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net...

Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to...

Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through...

with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements. An ocean current flows for great...

the change in the magnetic field that created it, and thus eddy currents react back on the source of the magnetic field. For example, a nearby conductive...

centre-backs, full-backs, sweepers, and wing-backs. The centre-back and full-back positions are most common in modern formations. The sweeper and wing-back roles...

News is information about current events. This may be provided through many different media: word of mouth, printing, postal systems, broadcasting, electronic...

Current TV was an American television channel which broadcast from August 1, 2005, to August 20, 2013. Prior INdTV founders Al Gore and Joel Hyatt, with...

current ratio, because a high current ratio indicates that the company is more likely to pay the creditor back. Large current ratios are not always a good...

indicates the adjusted totals based on current ticket prices (by Box Office Mojo). As of June 2011[update], the Back to the Future series is the 14th-highest-grossing...

A rip current (also rip) is a specific type of water current that can occur near beaches where waves break. A rip is a strong, localized, and narrow current...

the current retroflects (turns back on itself) in the Agulhas Retroflection due to shear interactions with the strong Antarctic Circumpolar Current, also...

Kuroshio Current (黒潮, "Black Tide"), also known as the Black Current or Japan Current (日本海流, Nihon Kairyū) is a north-flowing, warm ocean current on the...

Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on...

The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early...

Back-to-back filming is the practice of shooting two or more films as one production, thus reducing costs and time. Trilogies are common in the film industry...

force (counter EMF, CEMF, back EMF), is the electromotive force (EMF) manifesting as a voltage that opposes the change in current which induced it. CEMF...

monitoring. These latter are fed back over the current loop to the controller, using protocols such as HART. Analog current loops were historically occasionally...

would force the parcel immediately back into the main current that flows from west to east. Depth: The surface currents flow west. There is reversal point...
