- adj. a current or stream of electricity traversing a closed circuit formed of conducting substances, or passing by means of conductors from one body to another which is in a different electrical state.
- the movement of electrically charged particles, atoms, or ions, through solids, liquids, gases, or free space; the term is usually used of relatively smooth movements of electric charge through conductors, whether constant or variable. Sudden movements of charge are usually referred to by other terms, such as spark or lightning or discharge. In metallic conductors the electric current is usually due to movement of electrons through the metal. The current is measured as the rate of movement of charge per unit time, and is counted in units of amperes. As a formal definition, the direction of movement of electric current is considered as the same as the direction of movement of positive charge, or in a direction opposite to the movement of negative charge. Electric current may move constantly in a single direction, called direct current (abbreviated DC), or may move alternately in one direction and then the opposite direction, called alternating current (abbreviated AC).

Sorry, no etymologies found.
In the base of the tube — which was filled with explosive — was a thin iridio-platinum wire, and when the Director Layer pressed the trigger an electric current would flow across and fuse it, firing the explosive which would in turn explode the cordite charge.
Truly enough, it did seem as though his sterling nature rang in his genially dominant voice, and, again, as though his voice transmitted instantaneous waves of an electric current through every nerve of what, for want of a better phrase, I must perforce call his intensely alive hand.
In addition, Hoxa Sound, which he had been told was unguarded, was defended by hydrophones, which picked up the sound of approaching ships; by seabed cables, which caused a galvanometer needle to flick when an electric current was induced by the magnetic field of a crossing vessel; and by mines, which could be detonated electrically from the shore.
Hoxa Sound, which the submarine’s captain intended to enter, was defended by hydrophones that picked up the sound of all approaching ships, by seabed cables that caused the needle of a galvanometer to flick when an electric current was induced by the magnetic field of any crossing vessel, and by mines that could be detonated electrically from the shore.
The jury recommended death, and Judge Sylvester Close agreed, offering these chilling words to Yates: “An electric current will be sent through your body until you are determined to be dead.”
The radiant/far-infrared sauna uses a white hardwood room and an electric current to heat rods or panels, which then emit far-infrared invisible rays of energy which have wavelengths that are absorbed deeper into the body.
It is asserted that by sounding a certain note on a tuning-fork these noxious insects may be violently attracted by the sound, and by rigging up a screen through which an electric current can be sent, they may be slaughtered wholesale.
