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. Login
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 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.
The meaning of RESISTANCE is an act or instance of resisting : opposition. How to use resistance in a sentence.
Resistance refers to a measure of the opposition to current flow in a particular electrical circuit. The electrical resistance of an object refers to the measure of its opposition to the flow of electric current. The inverse quantity refers to the electrical conductance.
Sep 12, 2022 · Resistivity. When a voltage is applied to a conductor, an electrical field →E is created, and charges in the conductor feel a force due to the electrical field. The current density →J that results depends on the electrical field and the properties of the material. This dependence can be very complex.
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.
