`
`electrical characteristics
`
`electric transmission line Same as electric power transmis-
`sion line.
`
`electric tuning Same as electronic tuning.
`electric vector 1. in an electromagnetic field, the vector rep-
`resenting the electric field. The electric vector is perpen-
`dicular to the magnetic, or H, vector. Also called E vector.
`2. Same as electric field strength.
`trolley, or train,
`electric vehicle A vehicle, such as a car,
`which is propelled by electric power.
`In the case of a car,
`for instance, a fuel cell may provide the electricity which
`powers the motor, while an overhead cable may provide the
`electricity for a train. Its abbreviation is EV.
`electric~wave filter Same as electrical filter.
`electric waves Same as electromagnetic waves.
`electric wind An electric discharge in which a stream of
`charged particles moves away‘ from a body with a high volt-
`age, such as a Van tie Graaft‘ generator. Such a discharge
`may be visible or invisible. Also called convective dis-
`charge.
`electric wire An electric conductor composed of a single
`metallic strand, thread, or rod which is flexible and which
`usually has a circular cross section. Such a wire may or may
`not have insulation.
`
`electric wiring Also called wiring. 1. The system of wires
`and/or conductors that connect electrical components, cir-
`cuits, and devices together. For instance,
`the wires in a
`piece of electrical equipment, or the interconnections be-
`tween components of an IC. 2. The process of installing or
`manufacturing electric wiring (1).
`electrical All that pertains to and is correlated with electricity,
`but not having its physical properties or characteristics. For
`example, electrical symbols or electrical units. This con-
`trasts with electric, which is that containing, carrying, or
`producing electricity, or which is actuated by, based on, or
`arising from electricity. Nonetheless, even in technical us-
`age both terms are mostly interchangeably.
`electrical angle 1. An angle which specifies a given instant
`within a cycle of an alternating quantity, such as AC. Such
`an angle is usually expressed in electrical degrees, and a full
`cycle has 360°. 2. An angle which specifies a given phase
`difference between two altemating quantities. Expressed in
`electrical degrees.
`electrical appliance Same as electric appliance.
`electrical arc Same as electric arc.
`electrical attraction An attractive force between two oppo-
`sitely charged particles or bodies. For instance,
`that be-
`tween a cation and an anion.
`.Also called electric attrac-
`tion.
`
`electrical axis The axis along which electrical polarization
`occurs when a mechanical stress is applied to a piezoelectric
`crystal. Also called electric axis.
`electrical bandspread in a radio receiver, the use of a capaci-
`tor for improving selectivity, by spreading the bandwidth
`over a greater electrical range.
`electrical battery Same as electric battery.
`electrical breakdown Same as electric breakdown.
`
`electrical breakdown voltage Same as electric breakdown
`voltage.
`electrical bridge Same as electric bridge. '
`electrical cell Same as electric cell.
`
`electrical center The point at which at which an adjustable
`component, such as a variable resistor, is divided into two
`equal electrical values. Such a point does not necessarily
`occur at the physical center.
`electrical characteristics Measurable features, such as resis-
`tance, capacitance, and conductivity, which help describe
`the electrical properties of components, circuits, devices,

`
`ggs‘, such as those on DVDs and videocassettes. 2. Mu-
`"ecording of electric instruments, such as guitars and
`,' as opposed to nonelectric versions of said instru-
`,, 3. The recording on a given. medium, such as paper,
`assage of an electric current through it. A stylus
`‘a current, for instance, may be utilized. Also called
`ensitive recording.
`

`
`repulsion Same as electrical repulsion.
`"reset Same as electrical reset.
`ttzeresistance Same ‘as electrical resistance.
`resistivity Same as electrical resistivity.
`running The change in the direction of a radar beam
`gh variations in the phase and/or amplitu_de of the cur-
`led to the driven elements of its antenna away. Also
`.clcctrical scanning.
`reen
`_
`1. Same as electrostatic shielding (1).
`[he as electrostatic shielding (2).
`
`
`
`fséreening Same as electrostatic shielding.
`-shield
`1. Same as electrostatic shielding (1).
`me as electrostatic shielding" (2).
`“ti-.l’c.~‘shielding Same as electrostatic shielding.
`lc‘sliock The effect of a passage of current through
`"cg tissue. The effects of a shock can range from mild
`]_mg to death, depending on the strength of the current,
`points \vhere it enters and leaves the body, whether the
`is along its path, if the skin is wet, and so on. Under
`circumstances, a current of 0.1 ampere for l second
`ibe fatal. Electric shocks may also be utilized for thera-
`tic reasons, such as restoring the nomial rhythm to a
`which is twitching uncontrollably. Also called electri-
`tock, or shock (I).
`lcsignal Same as electrical signal.
`lc socket Same as electrical outlet.
`l spark A momentary luminous discharge of electricity
`veen two conductors separated by a gas, which is fre-
`Iy accompanied by a crackling noise. Used, for in-
`'t_a_nce, for ignition of fuel, or for machining. This contrasts
`an are (1), which has a more sustained duration. Also
`l:‘e_d-spark, spark discharge, or sparkover.
`starter A device utilized to start an electric motor,
`o accelerate it to its operational speed. Such a starter
`j/‘be powered, for example, by a battery. Also called
`rter (2).
`ic strength The maximum voltage a dielectric can \vith—
`rid before an abrupt increase in the electric current flow-
`ftiirougli it. May be expressed, for instance, in volts per
`l'meter. Also called dielectric strength, or dielectric
`sdity.
`lc stress Same as electric displacement.

`
`. Vic susceptibility A dimensionless quantity which meas-
`agree the ease with which a dielectric may be polarized.
`It is
`“me ratio of the dielectric polarization, to the product of the
`lcctric intensity multiplied‘ by the pennittivity of a vacuum.
`filso called dielectric susceptibility.
`lc switch A device which serves for opening, closing, or
`hanging connections in electric circuits. An electric switch
`y be manual or automatic. There are various types, in-
`ding mechanical, such as circuit-breakers, and semicon-
`._.uctor, such as transistors. Also called switch (1).
`ctric switchboard One or more panels which incorporate
`he switches, circuit-breakers, fuses, and the like, utilized to
`monitor and operate electric equipment.
`Also called
`witchboard (2).
`ctric system Same as electrical system.
`ctrlc transducer Same as electrical transducer.
`
`étric transient A momentary current or voltage that occurs
`_.\./hen the steady-state condition of a circuit has been dis-
`turbed. An example is a high-voltage spike.
