Definition of Resistance

"there are no relations of power without resistance" (1980, 142)

A balanced force and counter force between two bodies

(n.)
The quality of not yielding to force or external pressure; that power of a body which acts in opposition to the impulse or pressure of another, or which prevents the effect of another power; as, the resistance of the air to a body passing through it; the resistance of a target to projectiles.
  

(n.)
The act of resisting; opposition, passive or active.
  

(n.)
A means or method of resisting; that which resists.
  

(n.)
A certain hindrance or opposition to the passage of an electrical current or discharge offered by conducting bodies. It bears an inverse relation to the conductivity, -- good conductors having a small resistance, while poor conductors or insulators have a very high resistance. The unit of resistance is the ohm.

2. (physics) the quality of not yielding to force or external pressure; that power of a body which acts in opposition to the impulse or pressure of another, or which prevents the effect of another power; as, the resistance of the air to a body passing through it; the resistance of a target to projectiles.
3. a means or method of resisting; that which resists. unfold to us some warlike resistance.
4. (elec.) a certain hindrance or opposition to the passage of an electrical current or discharge offered by conducting bodies. it bears an inverse relation to the conductivity, -- good conductors having a small resistance, while poor conductors or insulators have a very high resistance. the unit of resistance is the ohm.
resistance
box (elec.), a rheostat consisting of a box or case containing a number of resistance coils of standard values so arranged that they can be combined in various ways to afford more or less resistance.
resistance
coil (elec.), a coil of wire introduced into an electric circuit to increase the resistance.

A stock that tends to find significant selling pressure at a certain price level is said to have overhead resistance at that price level. Technical indicators like moving averages can also provide resistance as downtrending stocks rally up to touch these trendlines and spark new sellers at such resistance points.

A horizontal price range where price hovers due to selling pressure before attempting a downward move.

See resistivity.

 Say it 
(The ability of a material to oppose the flow of an electric current , converting electrical energy into heat. The SI unit of resistance is the ohm .) Compare with conductivity .

The relative amount of heritable qualities possessed by a plant that reduces the degree of damage to the plant by a pest or pests.

Genetically inherited ability to withstand doses of pesticide which would kill individuals from strains whose ancestors had not been exposed to the pesticide.

With respect to plants: All properties enabling them to fight and overcome, partially or completely, the pathogenic effects of a disease or pest attack. This also includes 'tolerance', the ability of a plant to grow and develop in spite of pest or disease attack. With respect to pests and diseases: The ability of a pest population or disease to survive the poisonous effect of a pesticide.

(THERMAL) - The reciprocal of thermal conductance. See R-VALUE.

The property of a material to oppose the flow of current.

1. An opposing force.
2. A measure of a conductor's ability to retard the flow of electricity. Also see air resistance .

The opposition which limits the amount of current that can be produced by an applied voltage in an electrical circuit, measured in ohms.

The internal structure of wires even in the best conductors opposes the flow of electric current and converts some current into heat. This internal friction like effect is resistance and is measured in ohms. Resistance equals Voltage divided by Amperage.

Resistance

a measure given in ohms of the resistance to the flow of electric current.

The opposition of force to force.

Resistance is either lawful or unlawful. 1. It is lawful to resist one who is in the act of committing a felony or other crime, or who maliciously endeavors to commit such felony or crime. See self defence. And a man may oppose force to force against one who endeavors to make an arrest, or to enter his house without lawful authority for the purpose; or, if in certain cases he abuse such authority, and do more than he was authorized to do; or if it turn out in the result he has no right to enter, then the party about to be imprisoned, or whose house is about to be illegally entered, may resist the illegal imprisonment or entry by self-defence, not using any dangerous weapons, and may escape, be rescued, or even break prison, and others may assist him in so doing.

Resistance is unlawful when the persons having a lawful authority to arrest, apprehend, or imprison, or otherwise to advance or execute the public justice of the country, either civil or criminal, and using the proper means for that purpose, are resisted in so doing; and if the party guilty of such resistance, or others assisting him, be killed in the struggle, such homicide is justifiable; while on the other hand, if the officer be killed, it will, at common law, be murder in those who resist.

For plants and animals, the ability to withstand poor environmental conditions or attacks by chemicals or disease. May be inborn or acquired.

The opposition of a circuit to the flow of current . Resistance is measured in ohms, and can be calculated by dividing the voltage by current.

Opposition to the flow of DC current in a wire or electrical circuit.

The ability of some strains of bacteria, including M. tuberculosis, to grow and multiply in the presence of certain drugs that ordinarily kill them; such strains are referred to as drug-resistant strains.

The reduction, due to genetic selection, of susceptibility of a parasite or its vector to chemotherapy. The ability of a host to resist a pathogen

the ability of a microorganism to mutate or change its structure in such a way that it loses its sensitivity to a drug; a resistant organism can function and replicate despite the drug's presence. Contrast with susceptible. See also cross-resistance.

Reduction in a pathogen's sensitivity to a particular drug. Resistance is thought to result usually from a genetic mutation<!-- (see) -->. In HIV, such mutations can change the structure of viral enzymes<!-- (see) --> and proteins<!-- (see) --> so that an antiviral drug can no longer bind with them as well as it used to. Resistance detected by searching a pathogen's genetic makeup for mutations thought to confer lower susceptibility is called "genotypic resistance." Resistance that is found by successfully growing laboratory cultures of the pathogen in the presence of a drug is called "phenotype resistance."

The ability of a disease to overcome a drug. For example, after long-term use of AZT, HIV can develop strains of virus in the body that are no longer suppressed by this particular drug, and therefore are said to be resistant to AZT.
