- The horizontal movement of water caused by tides, wind and other forces.
- A certain progressive flowing of the sea in one direction, by which all bodies floating therein are compelled more or less to submit to the stream. the setting of the current, is that point of the compass towards which the waters run; and the drift of the current is the rate it runs at in an hour. currents are general and particular, the former
- [1] a steady flow of water in a definite horizontal direction. [2] the speed of such a flow. see also oceanic circulation.
- The movement of water,
- The flow of electrical charge.
- The movement of water, due to tides, river movement and circular currents caused by the motion of the earth.
- See electric current.
- The rate at which electricity flows in a conductor. analogous to the volume of water flowing through a pipe. measured in amperes, or amps. d

Current account, английский
- The broadest measure of trade, taking in receipts and payments from the trade in goods and services. the trade in services — or invisibles — such as banking and insurance is more important for developed countries, which is why the us and britain are particularly keen for developing countries to open up their service sectors.

Pantograph, английский
- An apparatus fixed to the roof of electric traction vehicles to draw current from the overhead supply.
- A scissors-like mechanism used for raising and lowering studio lights. other devices can also perform the same function, sometimes better.
- A drafting instrument for copying drawings, plans, etc., either on the same scale or on an enlarged or a reduced scale. pantry 1. a serving room between kitchen and dining space. 2. a room for storage of food supplies; a larder. 3. a room for preparing refreshments, not complete meals.
- Пантограф
- An instrument to copy or reduce drawings.
- Folding traction current collection device mounted on the roof of a vehicle on a railway employing an overhead supply system. nowadays, pantographs are sophisticated aero-dynamically designed devices which can operate at high speeds without loss of contact and with built-in safety devices which reduce the risk of damage to wires in the event of a fault. a common problem is when a pantograph catches above the wire and pulls it down for considerable distances before it is noticed by the crew and the train stopped. modern pantographs are fitted with automatic detection and lowering devices. the horns (curved edges) of the pantograph are equipped with frangible pneumatic sensors which, if broken by a wire support, cause the detector system to lower the pantograph.
- On train equipment for collecting electricity from overhead power cables.

Handing, английский
Term used to denote the orientation of a vehicle which may require identification of the direction it faces, e.g. a locomotive with a cab at one end only. particularly applies to some types of multiple unit vehicles which are semi-permanently coupled and which must face the right way round to allow the correct electrical and pneumatic connections to be made. handing is avoided by duplicating wiring and hoses on both sides at vehicle ends but gives rise to additional costs. handing is also used to denote the location of different items of equipment on a vehicle or train.
Centering device, английский
System provided to ensure that a coupler returns to a central position when released and thus make re-coupling easier. used particularly for automatic couplers.
