WAVEMETERS

Calibrated resonant circuits that are used to measure frequency [16]. An instrument for measuring the wavelength of an RF wave [18].


WEBER'S THEORY

A theory of magnetism which assumes that all magnetic material is composed of
many tiny magnets. A piece of magnetic material that is magnetized has all of the tiny magnets aligned so that the north pole of each magnet points in one direction [1].


WHEATSTONE BRIDGE

An ac bridge circuit used to measure unknown values of resistance, inductance, or capacitance [16].


WIDE-BAND AMPLIFIER

An amplifier designed to pass an extremely wide band of frequencies, such
as a video amplifier [8].


WINDOW

See SLOT [11].

WIRE

An insulated conductor, with low resistance to current flow, that is either solid or stranded [1] [4].

WIRING DIAGRAM

A diagram that shows the connections of an equipment or its component devices or parts. It may cover internal or external connections, or both, and contains such detail as is needed to make or trace connections that are involved [4].


WOBBLE FREQUENCY

The frequency at which an electron wobbles on its axis under the influence of
an external magnetic field of a given strength [11].


WORDS-PER-MINUTE

An approximate rate of speed. It means the number of five letter words with a
space between them that can be transmitted or received in a one-minute period [17].


WORK

The product of force and motion [1].
