Question

define the term of resistivity Give its si unit Draw graph for resistivity persist temperature​

Answer 1

The resistance of a given material is proportional to the length, but inversely proportional to the cross-sectional area. Thus resistivity can be expressed using the SI unit "ohm metre" (Ω⋅m) (i.e ohms divided by metres (for the length) and then multiplied by square metres (for the cross-sectional area..
