- Resistance - n. - The act of resisting; opposition, passive or active.
- Resistance - 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.
- Resistance - n. - A means or method of resisting; that which resists.
- Resistance - 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.
- Aluminium - n. - The metallic base of alumina. This metal is white, but with a bluish tinge, and is remarkable for its resistance to oxidation, and for its lightness, having a specific gravity of about 2.6. Atomic weight 27.08. Symbol Al.
- Tasimer - n. - An instrument for detecting or measuring minute extension or movements of solid bodies. It consists essentially of a small rod, disk, or button of carbon, forming part of an electrical circuit, the resistance of which, being varied by the changes of pressure produced by the movements of the object to be measured, causes variations in the strength of the current, which variations are indicated by a sensitive galvanometer. It is also used for measuring minute changes of temperature.
- Rheochord - n. - A metallic wire used for regulating the resistance of a circuit, or varying the strength of an electric current, by inserting a greater or less length of it in the circuit.
- Short circuit - - A circuit formed or closed by a conductor of relatively low resistance because shorter or of relatively great conductivity.
- Scrofula - n. - A constitutional disease, generally hereditary, especially manifested by chronic enlargement and cheesy degeneration of the lymphatic glands, particularly those of the neck, and marked by a tendency to the development of chronic intractable inflammations of the skin, mucous membrane, bones, joints, and other parts, and by a diminution in the power of resistance to disease or injury and the capacity for recovery. Scrofula is now generally held to be tuberculous in character, and may develop into general or local tuberculosis (consumption).
- Abutment - n. - A fixed point or surface from which resistance or reaction is obtained, as the cylinder head of a steam engine, the fulcrum of a lever, etc.
- Ftiction - n. - The resistance which a body meets with from the surface on which it moves. It may be resistance to sliding motion, or to rolling motion.
- Slip - n. - The motion of the center of resistance of the float of a paddle wheel, or the blade of an oar, through the water horozontally, or the difference between a vessel's actual speed and the speed which she would have if the propelling instrument acted upon a solid; also, the velocity, relatively to still water, of the backward current of water produced by the propeller.
- Reaction - n. - An action induced by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.
- Resistance - 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.
- Countertime - n. - The resistance of a horse, that interrupts his cadence and the measure of his manege, occasioned by a bad horseman, or the bad temper of the horse.
- Stasis - n. - A slackening or arrest of the blood current in the vessels, due not to a lessening of the heart's beat, but presumably to some abnormal resistance of the capillary walls. It is one of the phenomena observed in the capillaries in inflammation.
- Forearm - v. t. - To arm or prepare for attack or resistance before the time of need.
- Smooth - superl. - Causing no resistance to a body sliding along its surface; frictionless.
- Rebuff - v. t. - To beat back; to offer sudden resistance to; to check; to repel or repulse violently, harshly, or uncourteously.
- Ohm - n. - The standard unit in the measure of electrical resistance, being the resistance of a circuit in which a potential difference of one volt produces a current of one ampere. As defined by the International Electrical Congress in 1893, and by United States Statute, it is a resistance substantially equal to 109 units of resistance of the C.G.S. system of electro-magnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice 14.4521 grams in mass, of a constant cross-sectional area, and of the length of 106.3 centimeters. As thus defined it is called the international ohm.
- Rigidity - n. - The quality or state of being rigid; want of pliability; the quality of resisting change of form; the amount of resistance with which a body opposes change of form; -- opposed to flexibility, ductility, malleability, and softness.
- Indicator - n. - An instrument which draws a diagram showing the varying pressure in the cylinder of an engine or pump at every point of the stroke. It consists of a small cylinder communicating with the engine cylinder and fitted with a piston which the varying pressure drives upward more or less against the resistance of a spring. A lever imparts motion to a pencil which traces the diagram on a card wrapped around a vertical drum which is turned back and forth by a string connected with the piston rod of the engine. See Indicator card (below).
- Hysteresis - n. - A lagging or retardation of the effect, when the forces acting upon a body are changed, as if from velocity or internal friction; a temporary resistance to change from a condition previously induced, observed in magnetism, thermoelectricity, etc., on reversal of polarity.
- Coulomb - n. - The standard unit of quantity in electrical measurements. It is the quantity of electricity conveyed in one second by the current produced by an electro-motive force of one volt acting in a circuit having a resistance of one ohm, or the quantity transferred by one ampere in one second. Formerly called weber.
- Centreboard - n. - A movable or sliding keel formed of a broad board or slab of wood or metal which may be raised into a water-tight case amidships, when in shallow water, or may be lowered to increase the area of lateral resistance and prevent leeway when the vessel is beating to windward. It is used in vessels of all sizes along the coast of the United States
- Nonresistant - n. - One who maintains that no resistance should be made to constituted authority, even when unjustly or oppressively exercised; one who advocates or practices absolute submission; also, one who holds that violence should never be resisted by force.
- Rebellion - v. i. - The act of rebelling; open and avowed renunciation of the authority of the government to which one owes obedience, and resistance to its officers and laws, either by levying war, or by aiding others to do so; an organized uprising of subjects for the purpose of coercing or overthrowing their lawful ruler or government by force; revolt; insurrection.
- Microphone - n. - An instrument for intensifying and making audible very feeble sounds. It produces its effects by the changes of intensity in an electric current, occasioned by the variations in the contact resistance of conducting bodies, especially of imperfect conductors, under the action of acoustic vibrations.
- Stand - n. - To maintain an invincible or permanent attitude; to be fixed, steady, or firm; to take a position in resistance or opposition.
