Originating mainly from Oslofjord outflow, counterclockwise return flow of the Jutland Current within the Skaggerak, and outflow from the Kattegat, the Norway Coastal Current begins at about latitude 59°N, longitude 10°E and follows the coast of Norway, and is about 20 miles in width. Speeds are strongest off the southeast coast of Norway, where they frequently range between 1 and 2 knots. Along the remainder of the coast the current gradually weakens. It may widen to almost 30 miles at about latitude 63°N, where it joins the NORWAY CURRENT. South of latitude 62°N the current speed usually ranges between 0.4 and 0.9 knots. Speeds are generally stronger in spring and summer, when the flow is augmented by increased discharge from fjords.

OCEAN THERMAL-ENERGY CONVERSION

The conversion of energy arising from the temperature difference between warm surface water of oceans and cold deep-ocean current into electrical energy or other useful forms of energy. Abbreviated OTEC.

NULL-BALANCE RECORDER

An instrument in which a motor-driven slide wire in a measuring circuit is continuously adjusted so that the voltage or current to be measured will be balanced against the voltage or current from this circuit; a pen linked to the slide wire makes a graphical record of its position as a function of time.

NO-LOAD CURRENT

The current which flows in a network when the output is open-circuited.

NERNST-LINDEMANN CALORIMETER

A calorimeter for measuring specific heats at low temperatures, in which the heat reservoir consists of a metal of high thermal conductivity such as copper, to promote rapid temperature equalization; none of the material under study is more than a few millimeters from a metal surface, and the whole apparatus is placed in an evacuated vessel and heated by current through a platinum heating coil.

MULTIPLICATION

An increase in current flow through a semiconductor because of increased carrier activity.

MULTICHANNEL FIELD-EFFECT TRANSISTOR

A field-effect transistor in which appropriate voltages are applied to the gate to control the space within the current flow channels.

MOVING-CONDUCTOR LOUDSPEAKER

[ENG ACOUS] A loudspeaker in which the mechanical forces result from reactions between a steady magnetic field and the magnetic field produced by current flow through a moving conductor.

MOVING-COIL GALVANOMETER

Any galvanometer, such as the d'Arsonval galvanometer, in which the current to be measured is sent through a coil suspended or pivoted in a fixed magnetic field, and the current is determined by measuring the resulting motion of the coil.

MOS-CONTROLLED THYRISTOR

A type of thyristor in which there is a very thin metal oxide semiconductor (MOS) integrated circuit in the top surface of the high-power thyristor components, so that only a small gate current is needed.

MILLISECOND DELAY CAP

A delay cap with an extremely short (20500 thousandths of a second) interval between passing of current and explosion. Also known as short-delay detonator.
