Question

Calculate the area of cross section of a wire of length 2m, its resistance is 25Ω and the resistivity of material of wire is 1.84*10-6 Ωm.​

Answer 1

Answer:

14.72*10-8 m²

Explanation:

R = kL/A

A = kL/R = 1.84*10-6 Ωmx2m/25Ω = 14.72*10-8 m²

Answer 2

Answer:

hope it will help you

Explanation:

thank you
