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.
The meaning of RESISTANCE is an act or instance of resisting : opposition. How to use resistance in a sentence.
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.

Resistance We now consider the resistance of a wire or component. The resistance is a measure of how difficult it is to pass current through a wire or component. Resistance depends on the resistivity.
Resistance is a measure of how difficult it is for electrical current to flow through a material, and it is measured in ohms (Ω). The resistance of a material depends on its geometry (length, cross-sectional area, etc.) and its resistivity (ρ), which is a fundamental property of the material.
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.
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.
Resistance is measured in units called ohms, which is represented by the symbol Ω (an uppercase Greek letter omega). For example, a resistance of 10 ohms can be written as 10 Ω.
This article discusses resistance along with the resistance formula and its derivation. Resistance refers to the amount that an object impedes or resists in an electric current.
