Question

A wire of 1m long,0.2mm diameter and has a resistance od 10 ohm.Calculate the resistivity of the material

Answer 1

0.3 micro ohm per meter.

Answer 2

hello mate..

calculate it by

rho = R × A / l

take all the units in sI

si u have

rho = 10 × 0.01 × 10^-4 / 1

= 10^-5 ohm-m

please follow me if it helps u
