Web30 de set. de 2024 · On what factors resistivity depends? The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. The SI unit of electrical resistivity is the ohm-meter. Hence resistivity is dependent on the temperature. What is meant by 1 ohm? 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.

WebThe temperature dependence of the resistivity of semiconductors plays a significant role in their application in electronics. Electrical conductivity describes the ease at which electric current can pass through a material, and is an important parameter of a material. Conductors are the materials that allow current to pass through them. Web2 de abr. de 2024 · Note: The resistivity of a conductor depends only on the above mentioned three factors i.e., length, area of cross-section, and nature of the material of the conductor. Additionally, it also depends upon the physical conditions like temperature and pressure but is independent of its shape and size.
