* Electric current

Electric current is a flow of electric charge through a conductive medium.

Electric current is measured using an ammeter.

Electric current can be directly measured with a galvanometer, but this method involves breaking the electrical circuit, which is sometimes inconvenient.

Electric fields are the cause of several common phenomena, such as electric potential ( such as the voltage of a battery ) and electric current ( such as the flow of electricity through a flashlight ).

Electric arcs were used to provide illumination in the 19th century, but the arc current was unstable and they often produced hissing, humming or howling sounds.

Electric current through the conductor creates a magnetic flux proportional to the current.

Electric charge is an inextricable property of matter, so it appeared that some form of matter was required to provide the alternating current that would seem to have to exist at any point along the propagation path of the wave.

The Modicon brand was sold in 1977 to Gould Electronics, and later acquired by German Company AEG and then by French Schneider Electric, the current owner.

Transducer s convert signals from other physical waveform s to electrical Electric current | current or voltage waveforms, which then are processed, transmitted as electromagnetic wave s, received and converted by another transducer to final form.

Electric buses, which use twin trolley poles ( one for live current, one for return ) but have wheels with tyres rolling on a hard surface rather than tracks, are called trolleybuses, trackless trolleys ( particularly in the Northeastern U. S .), or sometimes ( in the UK, as well as in Seattle and Vancouver ) simply trolleys.

Electric current is carried by electrons in the external circuit.

Electric current from source to drain in a p-channel JFET is restricted when a voltage is applied to the gate.

General Electric Company ( backed by Thomas Edison and J. P. Morgan ) had proposed to power the electric exhibits with direct current originally at the cost of US $ 1. 8 million.

Electric currents that oscillate at radio frequencies have special properties not shared by direct current or alternating current of lower frequencies.

Electric current is used to strike an arc between the base material and consumable electrode rod, which is made of steel and is covered with a flux that protects the weld area from oxidation and contamination by producing carbon dioxide ( CO < sub > 2 </ sub >) gas during the welding process.

" The Soviet device used a magnetic field to confine the secondary electrons and relied on the Ag-O-Cs photocathode which had been demonstrated by General Electric in the 1920s.

Electric fields produced by charge distributions have a different character than those produced by changing magnetic fields.

The full set of corrections for SU ( 2 ) Yang – Mills theory was calculated by Nathan Seiberg and Edward Witten in Electric – magnetic duality, monopole condensation, and confinement in N = 2 supersymmetric Yang – Mills theory, in the process creating a subject that is today known as Seiberg-Witten theory.
