Previous section of "W" terms and definitions
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.
WEATHERPROOF: So constructed or protected that exposure to the weather will not interfere with
successful operation. Rainproof, raintight, or watertight equipment can fulfill the requirements for
weatherproof where varying weather conditions other than wetness, such as snow, ice, dust, or
temperature extremes, are not a factor.
WHEATSTONE BRIDGE. An ac bridge circuit used to measure unknown values of resistance,
inductance, or capacitance.
WIDE-BAND AMPLIFIER. An amplifier designed to pass an extremely wide band of frequencies, such
as a video amplifier.
WIRE. An insulated conductor, with low resistance to current flow, that is either solid or stranded. [Wire Manufacturers]
WIRE BRAID. Flexible wire constructed of small size strands
in tubular form. Used for shielding or connections where
constant flexing is required.
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.
WOBBLE FREQUENCY. The frequency at which an electron wobbles on its axis under the influence of
an external magnetic field of a given strength.
WORK. The product of force and motion.
WORKING VOLTAGE. The maximum voltage that a capacitor may operate at without the risk of
damage. [Dictionary of Capacitor Terms]
WYE (Y). A 3-phase connection in which one end of each phase winding is connected to a common point.
Each free end is connected to a separate phase wire. The diagram of this connection often resembles the
letter Y.
