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. Rain-proof, rain-tight, or water-tight 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. The resistor labeled Rx in the diagram is the component to be measured. |

WHITE NOISE. Noise having a frequency spectrum that is continuous and uniform over a specified frequency band.
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.
WIRE BUNDLE. Two or more wires bundled or grouped together to form a cable or group of wires.
Cable Wire Bundle
| Wire Wrapping. A method of attaching a wire between components with out using traces on a Printed Wiring Board [PWB]. The components are placed in a socket or pin which have a wire wrap terminal, while the board it self is blank with either holes or plated-through holes to accept the pins. The components are then interconnected by twisting wires around the wire wrap pins attached to the components. |

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. Similar to or identical to a schematic diagram.
WOBBLE FREQUENCY. The frequency at which an electron wobbles on its axis under the influence of an external magnetic field of a given strength.
WOOFER. A speaker designed to operate in the low frequency ranges, producing sound normally between 20Hz and 500Hz.
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 Capacitors]
WYE Connection Schematic
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.
