Plz solve this question in a some easy way ?? Share with your friends Share 0 Debalina Deb answered this Dear student, We have, Length of the wire, L = 1 mDiameter of the wire, d = 0.3 mm = (3 × 10-4 ) m Resistance, R = 26 Ω Resistivity, ρ = ? Now, we know,R =ρLA = ρLπd24⇒ρ = R × πd24L ⇒ρ= 26 ×π× (3 × 10-4 )24 ⇒ρ = 1.84 × 10-6 Ωmhence, at the given temperature, resistivity is 1.84 × 10-6 Ωm Regards, 0 View Full Answer
