polarity

listen to the pronunciation of polarity
Englisch - Englisch
either of the two extremes of such attributes
The dipole-dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule
the separation, alignment or orientation of something into two opposed poles
{n} a tendency to point to the pole
the orientation of magnetic or electric fields The polarity of the incoming audio signal determines the direction of movement of the speaker cone Must be observed when wiring speakers, so that they are "in phase" See Out of Phase
The direction of the magnetic field about a magnet, determined by the location of its North and South poles; every magnet has two equally stable polarities, obtained by interchanging its poles
See Polar, n
property of a molecule which describes the difference in location of the center of positive and center of negative charge on the molecule A nonpolar compound has these centers coinciding As they become further apart, the molecule becomes more polar
1) For batteries or direct current, an electrical condition determining the direction in which current tends to flow 2) For transformers, the designation of the relative instantaneous directions of the current entering the primary terminals and leaving the secondary terminals
The electrical condition or charge of a body, either negative or positive The central electrode of a torch battery is positive polarity
As applied to electric circuits, polarity indicates which terminal is positive and which is negative As applied to magnets, it indicates which pole is North and which pole is South
That quality or condition of a body in virtue of which it exhibits opposite, or contrasted, properties or powers, in opposite, or contrasted, parts or directions; or a condition giving rise to a contrast of properties corresponding to a contrast of positions, as, for example, attraction and repulsion in the opposite parts of a magnet, the dissimilar phenomena corresponding to the different sides of a polarized ray of light, etc
A condition which has two states (in or out) and is usually described in one of three ways: 1 Acoustical to electrical (microphone): Positive pressure at diaphragm produces positive voltage at pin 2 of XLR or at the tip of a ¼-inch phone plug 2 Electrical to acoustic: Positive voltage into the "plus" terminal of a speaker causes the speaker's diaphragm to move forward (produces positive pressure) 3 Electrical to electrical: Positive voltage into pin 2 of an XLR plug or at the tip of a ¼-inch phone plug produces positive voltage at the output (pin 2 of XLR jack, the tip of a ¼-inch phone plug, or the red (plus) connector of a binding post (banana terminal))
The tendency of a molecule to have positive and negative poles because of the unequal sharing of a pair of electrons
The direction or polarization of a signal entering or leaving a component For instance, if a positive signal is applied to the input of a device, and that device emits a positive signal, then it is said to be a non-inverting device Polarity merely describes a direction and should not be confused with phase (e g , It is important to maintain similar polarity throughout an entire speaker system so that all the speakers will be working together )
a relation between two opposite attributes or tendencies; "he viewed it as a balanced polarity between good and evil"
In electricity, refers to the condition of being either positive or negative
describes which side of an electrical circuit is the positive and which is the negative
Which side of an electrical circuit is the positive? Which is the negative? Polarity is the term describing which is which
If there is a polarity between two people or things, they are completely different from each other in some way. the polarities of good and evil
In electricity, refers to the condition of being either positive or negative 2
polarité = [French] polarity, from polus = [Latin] pole, from polos = [Greek] turning pointPolarity is a word that indicates one of two opposing choices In solar physics it is mostly used to distinguish whether magnetic field is pointing (somewhat) toward you or away from you This is called the magnetic polarity Read more about magnetic polarities on the Polarity Page
the sign of the potential (voltage) between two points in a circuit When a potential difference exists between two points, one end has a positive polarity and the other one, negative polarity Electrons flow from negative to positive, but by convention, current is considered to flow from positive to negative
The change or retention of the dark-to-light relationship of an image For example, going from a first- generation negative to a second-generation positive reverses polarity, whereas going from a first-generation negative to a second-generation negative maintains polarity See also NEGATIVE FILM, POSITIVE FILM
In electricity, the condition of being positive or negative
A designation of the relative instantaneous direction of the current in a secondary lead as compared with a primary lead The two leads are said to be of the same polarity when, at any instant, the currents in the two leads are flowing in the same direction as if the leads were a single piece of wire The polarity of a single-phase transformer is classed as either additive or subtractive
In electricity, the quality of having two oppositely charged poles, one positive one negative
having an indicated pole (as the distinction between positive and negative electric charges); "he got the polarity of the battery reversed"; "charges of opposite sign"
A speaker, for example, has a positive and a negative input terminal Connecting a battery directly to the speaker will result in the diaphragm moving outward If you reverse the battery leads, the diaphragm will move inward Caution: Too high of a voltage battery will also burn out the speaker!
A property of the conic sections by virtue of which a given point determines a corresponding right line and a given right line determines a corresponding point
– Ability of a power supply to produce an output that is positive or negative referenced to ground Also see Floating Output
Magnetically, opposite poles, north and south In electricity, oppositely charged poles, positive and negative
{i} presence of two opposing tendencies; state of having unequally distributed characteristics
The wiring of a microphone or speaker to make sure that the movement of air will be in the same direction as the electrical signal Also of concern between equipment in a balanced system
The designation of positive (+) or negative (-) electrical potential to the electrode
The sign of the voltage rise from a reference point (usually ground) to a point in a circuit
magnetic polarity
the state of being a north pole or south pole; the magnetic equivalent of electric charge
polarities
plural of polarity
