Atmospheric electricity
(gcide) | Electricity \E`lec*tric"i*ty\ ([=e]`l[e^]k*tr[i^]s"[i^]*t[y^]),
n.; pl. Electricities ([=e]`l[e^]k*tr[i^]s"[i^]*t[i^]z).
[Cf. F. ['e]lectricit['e]. See Electric.]
1. (Physics) a property of certain of the fundamental
particles of which matter is composed, called also
electric charge, and being of two types, designated
positive and negative; the property of electric charge on
a particle or physical body creates a force field which
affects other particles or bodies possessing electric
charge; positive charges create a repulsive force between
them, and negative charges also create a repulsive force.
A positively charged body and a negatively charged body
will create an attractive force between them. The unit of
electrical charge is the coulomb, and the intensity of
the force field at any point is measured in volts.
[PJC]
2. any of several phenomena associated with the accumulation
or movement of electrically charged particles within
material bodies, classified as static electricity and
electric current. Static electricity is often observed
in everyday life, when it causes certain materials to
cling together; when sufficient static charge is
accumulated, an electric current may pass through the air
between two charged bodies, and is observed as a visible
spark; when the spark passes from a human body to another
object it may be felt as a mild to strong painful
sensation. Electricity in the form of electric current is
put to many practical uses in electrical and electronic
devices. Lightning is also known to be a form of electric
current passing between clouds and the ground, or between
two clouds. Electric currents may produce heat, light,
concussion, and often chemical changes when passed between
objects or through any imperfectly conducting substance or
space. Accumulation of electrical charge or generation of
a voltage differnce between two parts of a complex object
may be caused by any of a variety of disturbances of
molecular equilibrium, whether from a chemical, physical,
or mechanical, cause. Electric current in metals and most
other solid coductors is carried by the movement of
electrons from one part of the metal to another. In ionic
solutions and in semiconductors, other types of movement
of charged particles may be responsible for the observed
electrical current.
[PJC]
Note: Electricity is manifested under following different
forms: (a)
Statical electricity, called also
Frictional electricity 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.
[1913 Webster]
3. The science which studies the phenomena and laws of
electricity; electrical science.
[1913 Webster]
4. Fig.: excitement, anticipation, or emotional tension,
usually caused by the occurrence or expectation of
something unusual or important. |

tide." --Chaucer.
[1913 Webster]

2. The alternate rising and falling of the waters of the
ocean, and of bays, rivers, etc., connected therewith. The
tide ebbs and flows twice in each lunar day, or the space
of a little more than twenty-four hours. It is occasioned
by the attraction of the sun and moon (the influence of
the latter being three times that of the former), acting
unequally on the waters in different parts of the earth,
thus disturbing their equilibrium. A high tide upon one
side of the earth is accompanied by a high tide upon the
opposite side. Hence, when the sun and moon are in
conjunction or opposition, as at new moon and full moon,
their action is such as to produce a greater than the
usual tide, called the spring tide, as represented in
the cut. When the moon is in the first or third quarter,
the sun's attraction in part counteracts the effect of the
moon's attraction, thus producing under the moon a smaller
tide than usual, called the neap tide.
[1913 Webster]
Note: The flow or rising of the water is called flood tide,
and the reflux, ebb tide.

\Har*mon"ic*al\ (-[i^]*kal), a. [L. harmonicus, Gr. "armoniko`s;
cf. F. harmonique. See Harmony.]
1. Concordant; musical; consonant; as, harmonic sounds.
[1913 Webster]
Harmonic twang! of leather, horn, and brass. --Pope.
[1913 Webster]
2. (Mus.) Relating to harmony, -- as melodic relates to
melody; harmonious; esp., relating to the accessory sounds
or overtones which accompany the predominant and apparent
single tone of any string or sonorous body.
[1913 Webster]
3. (Math.) Having relations or properties bearing some
resemblance to those of musical consonances; -- said of
certain numbers, ratios, proportions, points, lines,
motions, and the like.
[1913 Webster]
Harmonic interval (Mus.), the distance between two notes of
a chord, or two consonant notes.
Harmonical mean (Arith. & Alg.), certain relations of
numbers and quantities, which bear an analogy to musical
consonances.
Harmonic motion, the motion of the point A, of the foot of
the perpendicular PA, when P moves uniformly in the
circumference of a circle, and PA is drawn perpendicularly
upon a fixed diameter of the circle. This is simple
harmonic motion. The combinations, in any way, of two or
more simple harmonic motions, make other kinds of harmonic
motion. The motion of the pendulum bob of a clock is
approximately simple harmonic motion.
Harmonic proportion. See under Proportion.
Harmonic series or Harmonic progression. See under
Progression.
Spherical harmonic analysis, a mathematical method,
sometimes referred to as that of Laplace's Coefficients,
which has for its object the expression of an arbitrary,
periodic function of two independent variables, in the
proper form for a large class of physical problems,
involving arbitrary data, over a spherical surface, and
the deduction of solutions for every point of space. The
functions employed in this method are called spherical
harmonic functions. --Thomson & Tait.
Harmonic suture (Anat.), an articulation by simple
apposition of comparatively smooth surfaces or edges, as
between the two superior maxillary bones in man; -- called
also harmonia, and harmony.
Harmonic triad (Mus.), the chord of a note with its third
and fifth; the common chord.
