Specific Resistance Definition Physics
Specific Resistance Definition Physics. Specific resistance depends on the composition, temperature, pressure of the material. Resistance is the physical property of a substance because of which it opposes the flow of current i.e.
It was named in the honor of the famous german physicist georg simon ohm. Resistivity is commonly represented by the greek letter ρ. Specific resistance is an intrinsic property of a material that is dependent upon its composition.
The Unit Of Specific Resistance Is Ω M.
A low resistivity indicates a material that readily allows electric current. Resistance depends on the physical dimensions of the material, its composition, and temperature. Electric potential (electrostatic potential) and potential difference
Resistivity Is The Physical Property Of A Particular Substance Which Is Having Particular Dimensions.
N (physics) the volume of matter per unit mass; Resistance is defined as an opposition to current flow. The fundamental property resistivity or specific resistance is a measure of the resistance offered by a material.
However, There Is A Material Constant That Can Be Used To Find The Resistance Of Any Component Of A Specific Material.
Specific resistance is an intrinsic property of a material that is dependent upon its composition. A material's resistivity is a scalar quantity. An electric current flows when electrons move through a conductor, such as a metal wire.
Specific Resistance Depends On The Composition, Temperature, Pressure Of The Material.
The wires and the other components in a circuit reduces the flow of charge through them. Resistance is a sample constant, so is specific to individual components. R=ρ, if a and l =1 in equation r= ρ (l/a).
Resistance Is The Physical Property Of A Substance Because Of Which It Opposes The Flow Of Current I.e.
Its si unit is ohm meter (ω m). It was named in the honor of the famous german physicist georg simon ohm. Here, ρ is called the electrical resistivity or specific resistance of the material.
