dipola

listen to the pronunciation of dipola
التركية - الإنجليزية
dipole
any object (such as a magnet, polar molecule or antenna), that is oppositely charged at two points (or poles)
A monopole with a ground balance (mirror image)
{i} (Physics, Electronics) pair of magnetic poles; (Physical Chemistry) molecule with two poles
Magnetized object that possesses north and south magnetic poles A bar magnet and Earth are two examples
Antenna fed from the center (Name often applied to "rabbit ear" antenna )
a pair of equal and opposite electric charges or magnetic poles separated by a small distance
A speaker design which generates equal amounts of sound both forward and backward, with the two sounds being out of phase Dipoles are often used as surround speakers See also Bipole
A molecule which has a definite separation between its center of positive charge and center of negative charge Such a molecule is said to be polar A polar species will be more attracted to a charged species than will a non-polar one
A speaker where the sound emanates from the sides of the monitors, which provides the advantage of additional coverage area A Dipole works well for ambience material but not as well for direct source material
Refers to the separation of charge between two covalently bonded atoms
Anything with two equal but opposite electrical charges, such as the positive and negative ends of a polar bond or molecule
A type of antenna with two defined opposing radiating elements, both of the proper length for the frequency of operation, and each forming the counterpoise for the other
an aerial half a wavelength long consisting of two rods connected to a transmission line at the center
a basic antenna element to which most other antennas are compared for gain
a compact source of magnetic force, with two magnetic poles A bar magnet, coil or current loop, if their size is small, create a dipole field The Earth's field, as a crude approximation, also resembles that of a dipole, located near the Earth's center
A type of low-gain (2 2-dBi) antenna consisting of two (often internal) elements
A speaker which radiates sound primarily in opposite directions, 180 degrees out of phase,  This creates a null, or area with no sound, to the sides of the speaker Such designs are engineered by using drivers wired out of phase, or by using both sides of a flat driver
An open-back speaker that radiates sound equally front and rear The front and rear waves are out of phase and cancellation will occur when the wavelengths are long enough to "wrap around" The answer is a large, wide baffle or to enclose the driver creating a monopole
Anything with two equal but opposite electrical charges, e g the positive and negative ends of a polar bond or molecule
A pair of equal and opposite electrical charges separated by a small distance A dipole will align itself, if possible, in the presence of other electrical charges according to the attraction of opposite and repulsion of like charges Externally electrically neutral chemical molecules can have a dipole inside E g , water is a triangular molecule with the oxygen at one corner and the two hydrogens at the other two corners The internal charge distribution is such that the hydrogen side has a slight excess of positive charge and the oxygen end is correspondingly negative A dipole is characterized by its "dipole moment," the product of the charge and the separation distance (coulomb times centimeter)
