Question

calculate the area of cross section of a wire if its length is 1 m its resistance is 23 ohm and the resistivity of the material of the wire is 1.84 into 10 to the power minus 6 ohm m

Answer 1

8*10 to the power minus 8 m square is the area of the cross section

Answer 2

Formula:- $R = Pl/A$

$23 = 1.84 * 10^{-6} * 1 /A$

$23A = 1.84 * 10^{-6}$

$A = 1.84 * 10^{-6} / 23$
