The meaning of RESISTANCE is an act or instance of resisting : opposition. How to use resistance in a sentence.
a force that acts to stop the progress of something or make it slower: The car's speed was reduced by air / wind resistance. [ C or U ] physics specialized. the degree to which a substance prevents the flow of an electric current through it: Copper has (a) low resistance. Fewer examples.
May 30, 2024 · Resistance, in electricity, property of an electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductors.
The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction.
Review the key terms, equations, and skills related to current, resistance, and resistivity, including how to find the current direction and what resistance depends on.
A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms. Good conductors, such as copper, have low resistance. Good insulators, such as rubber, have high resistance.
RESISTANCE meaning: 1 : refusal to accept something new or different often + from often + to; 2 : effort made to stop or to fight against someone or something
resistance. [uncountable, singular] dislike of or opposition to a plan, an idea, etc.; the act of refusing to obey. As with all new ideas it met with resistance. resistance to somebody/something There has been a lot of resistance to this new law.
Opposition of some force, thing, etc. to another or others. A force that retards, hinders, or opposes motion. Power or capacity to resist; specif., the ability of an organism to ward off disease. A process in which the ego opposes the conscious recall of anxiety-producing experiences.
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
