what is resistivity and what its unit |
|
Answer» SI unit of restivity is ohm.m \tThe resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. The unit for resistivity is the ohm-metre.\tThe resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.\tA good conductor has less resistivity, whereas a bad conductor or insulator has high resistivity. The property of conductor to resist the flow of the charge through it is called resistivity the si unit is ohm |
