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 rate of flow of electric charge through a surface.
In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field.
A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.
Michael Faraday was born on 22 September 1791 in Newington Butts, [7] Surrey, which is now part of the London Borough of Southwark. [8] His family was not well off. His father, James, was a member of the Glasite sect of Christianity.
Brush Electric Company's central power plant with dynamos generating direct current to power arc lamps for public lighting in New York. Beginning operation in December 1880 at 133 West Twenty-Fifth Street, the high voltages it operated at allowed it to power a 2-mile (3.2 km) long circuit.
Mains electricity, utility power, grid power, domestic power, wall power, household current, [2] or, in some parts of Canada, hydro, is a general-purpose alternating-current (AC) electric power supply.
Byford Dolphin was a semi-submersible, column-stabilised drilling rig operated by Dolphin Drilling, a subsidiary of Fred Olsen Energy.Byford Dolphin was registered in Hamilton, Bermuda, [1] and drilled seasonally for various companies in the British, Danish, and Norwegian sectors of the North Sea.
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] ...
