Voltaic \Vol*ta"ic\, a. [Cf. F. volta["i]que, It. voltaico.]
1. Of or pertaining to Alessandro Volta, who first devised
apparatus for developing electric currents by chemical
action, and established this branch of electric science;
discovered by Volta; as, voltaic electricity.
2. Of or pertaining to voltaism, or voltaic electricity; as,
voltaic induction; the voltaic arc.
Note: See the Note under {Galvanism}.
{Voltaic arc}, a luminous arc, of intense brilliancy, formed
between carbon points as electrodes by the passage of a
powerful voltaic current.
{Voltaic battery}, an apparatus variously constructed,
consisting of a series of plates or pieces of dissimilar
metals, as copper and zinc, arranged in pairs, and
subjected to the action of a saline or acid solution, by
which a current of electricity is generated whenever the
two poles, or ends of the series, are connected by a
conductor; a galvanic battery. See {Battery}, 4.
(b), and Note.
{Voltaic circuit}. See under {Circuit}.
{Voltaic couple} or {element}, a single pair of the connected
plates of a battery.
{Voltaic electricity}. See the Note under {Electricity}.
{Voltaic pile}, a kind of voltaic battery consisting of
alternate disks of dissimilar metals, separated by
moistened cloth or paper. See 5th {Pile}.
{Voltaic protection of metals}, the protection of a metal
exposed to the corrosive action of sea water, saline or
acid liquids, or the like, by associating it with a metal
which is positive to it, as when iron is galvanized, or
coated with zinc.
Electricity \E`lec*tric"i*ty\, n.; pl. {Electricities}. [Cf. F.
['e]lectricit['e]. See {Electric}.]
1. A power in nature, a manifestation of energy, exhibiting
itself when in disturbed equilibrium or in activity by a
circuit movement, the fact of direction in which involves
polarity, or opposition of properties in opposite
directions; also, by attraction for many substances, by a
law involving attraction between surfaces of unlike
polarity, and repulsion between those of like; by
exhibiting accumulated polar tension when the circuit is
broken; and by producing heat, light, concussion, and
often chemical changes when the circuit passes between the
poles or through any imperfectly conducting substance or
space. It is generally brought into action by any
disturbance of molecular equilibrium, whether from a
chemical, physical, or mechanical, cause.
Note: Electricity is manifested under following different
forms: (a)
{Statical electricity}, called also
{Frictional or Common}, {electricity}, electricity in the
condition of a stationary charge, in which the disturbance
is produced by friction, as of glass, amber, etc., or by
induction. (b)
{Dynamical electricity}, called also
{Voltaic electricity}, electricity in motion, or as a current
produced by chemical decomposition, as by means of a
voltaic battery, or by mechanical action, as by
dynamo-electric machines. (c)
{Thermoelectricity}, in which the disturbing cause is heat
(attended possibly with some chemical action). It is
developed by uniting two pieces of unlike metals in a bar,
and then heating the bar unequally. (d)
{Atmospheric electricity}, any condition of electrical
disturbance in the atmosphere or clouds, due to some or
all of the above mentioned causes. (e)
{Magnetic electricity}, electricity developed by the action
of magnets. (f)
{Positive electricity}, the electricity that appears at the
positive pole or anode of a battery, or that is produced
by friction of glass; -- called also {vitreous
electricity}. (g)
{Negative electricity}, the electricity that appears at the
negative pole or cathode, or is produced by the friction
of resinous substance; -- called also resinous
electricity. (h)
{Organic electricity}, that which is developed in organic
structures, either animal or vegetable, the phrase animal
electricity being much more common.
2. The science which unfolds the phenomena and laws of
electricity; electrical science.
3. Fig.: Electrifying energy or characteristic.
