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.
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.
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
Sep 12, 2022 · The resistivity of a material is a measure of how strongly a material opposes the flow of electrical current. The symbol for resistivity is the lowercase Greek letter rho, ρ, and resistivity is the reciprocal of electrical conductivity: ρ = 1 σ. The unit of resistivity in SI units is the ohm-meter (Ω ⋅ m.
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.
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.
any mechanical force that tends to retard or oppose motion. see more. noun. the action of opposing something that you disapprove or disagree with. “he encountered a general feeling of resistance from many citizens”. synonyms: opposition. see more. noun. group action in opposition to those in power.
Electrical resistance is defined as the property of an electrical component to resist the flow of electric current. The unit of electrical resistance is ohm which is defined as volt per ampere.
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.
