Question

Obtain an expression for resistivity of an material

Answer 1

Answer:

HELLO BUDDY❤

Resistance R of a conductor depends on the length l and area of cross section A of the conductor Where, (rho) is called resistivity of the conductor it is also called as specific resistance. If we put l=1m andA=1sq. m. then we get, R=ρ.
