The dimensions of a block are (1 cm × 1 cm × 100 cm) the specific resistance of its material is `3xx10^(-7)` ohm × metre. Then resistance between the rectangular faces is :-

`3xx10^(-9) Omega`

`3xx10^(-7) Omega`

`3xx10^(-5) Omega`

`3xx10^(-3) Omega`

Text Solution

Verified by Experts

The correct Answer is:

`R=(rhol)/A`
put l=1 cm
A=1 cm x 100 cm
