what is resistivity write its SI unit on what factors it depend
Answers
====================================
The resitivity of the material is the resistance of that conductor in per unit length and per unit cross sectional area.
The resitivity of a conductor is can be find by using Formula :
Resistivity = Resistance ×( Area of cross section /lenth of the wire)
SI Unit of Resistivity is ohm- metre.
Resistivity of a material is depends upon the factors .
1) Nature of the conductor
2) Temperature of the conductor
But it is not depend upon the shape and size of the conductor
Answer:
The 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. The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. A good conductor has less resistivity. On the other hand, a bad conductor or insulator has high resistivity. The length of the wire – increasing the length increases the resistance. HOPE IT HELPS U PLS MARK ME BRAINLIEST
