Question

write the relation between resistance and electrical resistivity of the material of a conductor in the shape of cylinder of length L and area of cross section has derived the SI unit of electrical resistivity​

Answer 1

ro= (R×l)÷area

specific resistance is equal to the product of resistance and area divided by length.

Answer 2

R=€L/A

V/I=€L/A

(W/Q)/(Q/T)=€L/L*L

€=W*L*T/(Q*Q)

€=electrical resistivity
