Please solve the question provided in the picture. Fast it's urgent!!!
Just find the resistivity...

I will mark the appropriate answer as BRAINLIEST......

Answer 1

We have,

Resistance of wire = 26 ohm

Diameter = 0.3mm = 3 x 10⁻⁴m

Length = 1 m

We know,

Resistance = ρl / A

               R = ρL / A

               RA / L = ρ

               ρ = Rπd / L

Substituting the values, We get,

ρ = 1.84 x 10⁻⁸ ohm m
