Question

What will be the resistivity of a metal wire of 2m length and o.6mm in diameter , if the resistance of the wire is 50 ohm

Answer 1

Answer:

0.0471ohmm

Explanation:

Given resistance R=50ohm

Length l=2m

Radius r=0.0006

p=50*3.14*0.0006/2=0.0471ohmm

Answer 2

Answer:

7.065 x 10 ^ -6 ohm.m

Explanation:

For Explanation Refer to the Respective Attachment.
