Question

Resistance of a metal wire of length 1 m is 36 ohm at 20°C if the diameter of the wire is 0.3 mm what will be the resistivity of the metal at that temperature? Predict the material of the wire also.

(please explain each step in detail)

please someone answer, please ^_^

Answer 1

calculation do you. solution look in photo.

explanation in notes

shi hai tho aur questions puchne ke liye follow karo

Answer 2

$resistivity of the metal at that temperature =\\\frac{R(pi)r^{2} }{l} \\=36*\frac{22}{7} *(1.5*10^{-4}) }^{2} \\= ****calculate *****$
