Let us have a close look of effect of temperature on resistivity of different types of substances …
WebResistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA /l. The unit of resistance is the ohm. In the metre-kilogram-second (mks) system, the ratio of area in square metres to length in ... Web5 de abr. de 2024 · Resistivity of a material is the ability of the material to show resistance. Resistance in terms of resistivity is shown as follows: R = ρ l A Here, R is the resistance of the conductor, ρ is the resistivity of the material, l is the length of the conductor and A is the area of the conductor.
WebThe resistivity ρ of a material depends on the molecular and atomic structure and is temperature-dependent. For many good conductors, resistivity increases with increasing temperature. Variation of Resistivity in Conductors In conductors, valence electrons are loosely bound to the nucleus. WebBasically resistivity depends on the availability of free electrons and their mobility in material. Both these arise from molecular or atomic structure of material. This structure decides the ease with which electrons or charges can move / drift in the material under the influence of electric field or applied voltage.
