VAR

Abbreviation for volt-amperes reactive [2].

VARACTOR

A PN junction semiconductor, designed for microwave frequencies, in which the capacitance varies with the applied voltage [7] [11] [12].

VARACTOR FM MODULATOR

An FM modulator that uses a voltage-variable capacitor (varactor) [12].

VARIABLE

A representative symbol that can assume any of a given set of values [13].

VARIABLE ATTENUATOR

An attenuator for reducing the strength of an ac signal either continuously
or in steps, without causing signal distortion [11].

VARIABLE RESISTOR

A wire-wound or composition resistor, the value of which may be changed over
a designed range [1].

VARIABLE-MU-TUBE

Same as REMOTE-CUTOFF TUBE [6].

VARNISHED CAMBRIC

Cotton cloth coated with insulation varnish. An insulation used on high-
voltage conductors [4].

VECTOR

A line used to represent both direction and magnitude [2] [12].

VEITCH DIAGRAM

A diagram consisting of joined squares, which is used to give a graphic
representation of basic logic relations [13].
