The specific resistance of manganin is `50 xx 10^(-8)Omega` m.
The resistance of a cube of length 50 m will be:

A

`10^(-6) Omega `

B

`2.5 xx 10^(-5) Omega `

C

`10^(-8) Omega `

D

`50 xx10^(-8) Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
` 50 xx 10^(-8) Omega `
Explanation : Specific resistance does not depend upon area and length . Therefore , the value will remain constant i.e., `50 xx 10^(-8) Omega m `
